Oklahoma City bombing

On April 19, 1995, American anti-government extremist Timothy McVeigh, assisted by Terry Nichols, detonated a makeshift bomb stored in a rental truck parked in front of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, in an act of domestic terrorism. The explosion killed 167 people, injured 684, and destroyed more than a third of the building. The attack also destroyed or damaged 324 other buildings, destroyed 86 vehicles and caused an estimated $652 million in damage. During rescue operations after the bombing, a rescue worker was killed after being struck on the head by falling debris, bringing the total death toll to 168.

Within 90 minutes of the explosion, McVeigh was stopped by Oklahoma Highway Patrolman Charlie Hanger for driving without a front license plate and arrested for illegal weapons possession. Forensic evidence quickly linked McVeigh and Nichols to the attack; within days, both men were charged. Michael and Lori Fortier were later identified as accomplices. McVeigh, a combat veteran of the Gulf War, rented a Ryder truck, which he later filled with the explosives used in the attack. Nichols had assisted McVeigh in planning the attack, and in making the bomb. McVeigh and Nichols were primarily motivated by their anger at the U.S. federal government, particularly its handling of the law enforcement sieges at Ruby Ridge in 1992 and Waco in 1993, as well as the 1994 Federal Assault Weapons Ban. McVeigh had timed the retaliatory attack to coincide with the second anniversary of the end of the siege in Waco and the Battles of Lexington and Concord, the first engagements of the American Revolutionary War.

The official Federal Bureau of Investigation (FBI) report on the bombing, referred to as "OKBOMB", involved 28,000 interviews, 7,100 lbs (3,200 kg) of evidence, and nearly one billion pieces of information. When the FBI raided McVeigh's home, they found a telephone number that led them to a farm where McVeigh had purchased supplies for the bombing. The bombers were tried and convicted in 1997. McVeigh was sentenced to death; he was executed via lethal injection on June 11, 2001, at the U.S. federal penitentiary in Terre Haute, Indiana. Nichols was sentenced to life in prison without the possibility of parole. In response to the bombing, U.S. Congress passed the Antiterrorism and Effective Death Penalty Act of 1996, which limited access to habeas corpus in the United States, among other provisions. It also passed legislation to increase the protection around federal buildings to deter future terrorist attacks. The bombing remains the deadliest act of domestic terrorism in U.S. history and was the deadliest terrorist attack in U.S. history until the September 11 attacks.

The chief conspirators, Timothy McVeigh and Terry Nichols, met in 1988 at Fort Benning during basic training for the U.S. Army. McVeigh met Michael Fortier as his Army roommate. The three shared interests in survivalism. McVeigh and Nichols were radicalized by white supremacist and antigovernment propaganda. They expressed anger at the federal government's handling of the 1992 Federal Bureau of Investigation (FBI) standoff with Randy Weaver at Ruby Ridge, as well as the Waco siege, a 51-day standoff in 1993 between the FBI and Branch Davidian members that began with a botched Bureau of Alcohol, Tobacco, and Firearms (ATF) attempt to execute a search and arrest warrant. There was a shootout and ultimately a siege of the compound, resulting in the burning and shooting deaths of David Koresh and 81 others. In March 1993, McVeigh visited the Waco site during the standoff, and again after the siege ended. He later decided to bomb a federal building as a response to the raids and to protest what he believed to be U.S. government efforts to restrict the rights of private citizens, particularly those under the Second Amendment. McVeigh had stated that federal agents were acting like soldiers, thus making an attack on a federal building, an attack on their “command centers.”thumb|left|upright|Alfred P. Murrah Federal Building

McVeigh later said that, instead of bombing a building, he had contemplated a “campaign of individual assassination.” Potential targets in this campaign included United States Attorney General Janet Reno and FBI Hostage Rescue Team sniper Lon Horiuchi. He initially intended to destroy only a federal building, but he later decided that his message would be more powerful if many people were killed in the bombing. McVeigh's criterion for attack sites was that the target should house at least two of these three federal law enforcement agencies: the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the Federal Bureau of Investigation (FBI), and the Drug Enforcement Administration (DEA). He regarded the presence of additional law enforcement agencies, such as the Secret Service or the U.S. Marshals Service, as a bonus.

A resident of Kingman, Arizona, McVeigh considered targets in Missouri, Arizona, Texas, and Arkansas. He said in his authorized biography that he wanted to minimize non-governmental casualties, so he ruled out Simmons Tower, a 40-story building in Little Rock, Arkansas, because a florist's shop occupied space on the ground floor. In December 1994, McVeigh and Fortier visited Oklahoma City to inspect what would become the target of their campaign: the Alfred P. Murrah Federal Building. Prior to his execution, Snell predicted that a bombing would take place that day.thumb|A detailed map of [[Herington, Kansas, the general location where McVeigh and Nichols stored the ammonium nitrate fertilizer used for the construction of the bomb. The storage unit was located along US Highway 77, adjacent to a Pizza Hut.]]

McVeigh and Nichols bought or stole the materials they needed to manufacture the bomb and stored them in rented sheds. In August 1994, McVeigh obtained nine binary-explosive Kinestiks from gun collector Roger E. Moore in Arkansas, and with Nichols ignited the devices outside Nichols's home in Herington, Kansas. On September 30, 1994, Nichols bought forty bags of ammonium nitrate fertilizer from Mid-Kansas Coop in McPherson, Kansas, enough to fertilize of farmland at a rate of of nitrogen per acre (.4 ha), an amount commonly used for corn. Nichols bought an additional bag on October 18, 1994.

McVeigh and Nichols then robbed Moore in his home of $60,000 worth of guns, gold, silver, and jewels, transporting the property in the victim's van.

In October 1994, McVeigh showed Michael and his wife Lori Fortier a diagram he had drawn of the bomb he wanted to build.

The next round of the NHRA championship tour was the Chief Auto Parts Nationals at the Texas Motorplex in Ennis, Texas, where McVeigh posed as a motorcycle racer and attempted to purchase nitromethane on the pretext that he and some fellow bikers needed it for racing. However, there were no nitromethane-powered motorcycles at the meeting, and he did not have an NHRA competition license. Lesueur again refused to sell McVeigh the fuel because he was suspicious of McVeigh's actions and attitudes, but VP Racing Fuels representative Tim Chambers sold McVeigh three barrels. Chambers questioned the purchase of three barrels, when typically no more than five gallons would be purchased by a Top Fuel Harley rider, and the class was not even raced that weekend.

McVeigh rented a storage space in which he stockpiled seven crates of Tovex “sausages,” 80 spools of shock tube, and 500 electric blasting caps, which he and Nichols had stolen from a Martin Marietta Aggregates quarry near Marion, Kansas. He decided not to steal any of the of ANFO (ammonium nitrate/fuel oil) he found at the scene, as he did not believe it was powerful enough (he did obtain 17 bags of ANFO from another source for use in the bomb). McVeigh made a prototype bomb that was detonated in the desert to avoid detection.

Later, speaking about the military mindset with which he went about the preparations, he said, "You learn how to handle killing in the military. I face the consequences, but you learn to accept it." He compared his actions to the atomic bombings of Hiroshima and Nagasaki, rather than the attack on Pearl Harbor, reasoning it was necessary to prevent more lives from being lost.

Grandview Plaza, the former location of the Dreamland Motel where McVeigh stayed, is just to the east of Junction City along Interstate 70 (pink).]]

On April 14, 1995, McVeigh paid for a room at the Dreamland Motel in Junction City, Kansas. The next day, he rented a 1993 Ford F-700 truck from Ryder under the name Robert D. Kling, an alias he adopted because he knew an Army soldier named Kling with whom he shared physical characteristics, and because it reminded him of the Klingon warriors of Star Trek. On April 16, he and Nichols drove to Oklahoma City, where he parked a getaway car, a yellow 1977 Mercury Marquis, several blocks from the Murrah Federal Building. The nearby Regency Towers Apartments' lobby security camera recorded images of Nichols' blue 1984 GMC pickup truck on April 16. After removing the car's license plate, he left a note covering the vehicle identification number (VIN) plate that read, "Not abandoned. Please do not tow. Will move by April 23. (Needs battery & cable)." Specifically, McVeigh arranged the barrels in the shape of a backwards "J"; he later said that for pure destructive power, he would have put the barrels on the side of the cargo bay closest to the Murrah Building; however, such an unevenly distributed load might have broken an axle, flipped the truck over, or at least caused it to lean to one side, which could have drawn attention. All or most of the barrels of ANNM (ammonium nitrate–nitromethane mixture) contained metal cylinders of acetylene intended to increase the fireball and the brisance of the explosion. The use of a Ryder truck and the bomb material was an extremely similar technique used in the 1993 World Trade Center bombing and it's been proposed they were inspired by the event to replicate their use of a truck and similar bombs in the Oklahoma bombing.

McVeigh then added a dual-fuse ignition system accessible from the truck's front cab. He drilled two holes in the cab of the truck under the seat, while two more holes were drilled in the body of the truck. One green cannon fuse was run through each hole into the cab. These time-delayed fuses led from the cab through plastic fish-tank tubing conduit to two sets of non-electric blasting caps which would ignite around of the high-grade explosives that McVeigh stole from a rock quarry. The tubing was painted yellow to blend in with the truck's livery, and duct-taped in place to the wall to make it harder to disable by yanking from the outside. The fuses were set up to initiate, through shock tubes, the of Tovex Blastrite Gel sausages, which would in turn set off the configuration of barrels. Of the 13 filled barrels, nine contained ammonium nitrate and nitromethane, and four contained a mixture of the fertilizer and about of diesel fuel. Additional materials and tools used for manufacturing the bomb were left in the truck to be destroyed in the blast. After finishing the truck bomb, the two men separated; Nichols returned home to Herington and McVeigh traveled with the truck to Junction City. The bomb cost about to make.

McVeigh's original plan had been to detonate the bomb at 11 a.m., but at dawn on April 19, 1995, he decided instead to destroy the building at 9 a.m. As he drove toward the Murrah Federal Building in the Ryder truck, McVeigh carried with him an envelope containing pages from The Turner Diaries—a fictional account of white supremacists who ignite a revolution by blowing up the FBI headquarters at 9:15 one morning using a truck bomb. to Thomas Jefferson, "When the government fears the people, there is liberty. When the people fear the government, there is tyranny." Underneath, McVeigh had written, "Maybe now, there will be liberty!" with a hand-copied quote by John Locke asserting that a man has a right to kill someone who takes away his liberty. At the same moment, McVeigh lit the five-minute fuse. Three minutes later, still a block away, he lit the two-minute fuse. He parked the Ryder truck in a drop-off zone situated under the building's day-care center, exited, and locked the truck. As he headed to his getaway vehicle, he dropped the keys to the truck a few blocks away.

At 9:02 a.m. (14:02 UTC), the Ryder truck, containing over of ammonium nitrate fertilizer, nitromethane, and diesel fuel mixture, detonated in front of the north side of the nine-story Alfred P. Murrah Federal Building. In total, 168 people were killed and hundreds more injured. One-third of the building was destroyed by the explosion, which created a , crater on NW 5th Street next to the building. The blast destroyed or damaged 324 buildings within a four-block radius, and shattered glass in 258 nearby buildings. The broken glass alone accounted for five percent of the death total and 69 percent of the injuries outside the Murrah Federal Building. Seismometers at the Omniplex Science Museum in Oklahoma City, away, and in Norman, Oklahoma, away, recorded the blast as measuring approximately 3.0 on the Richter magnitude scale.

The collapse of the northern half of the building took roughly seven seconds. As the truck exploded, it first destroyed the column next to it, designated as G20, and shattered the entire glass facade of the building. The shockwave of the explosion forced the lower floors upwards, before the fourth and fifth floors collapsed onto the third floor, which housed a transfer beam that ran the length of the building and was being supported by four pillars below, as well as supporting the pillars that hold the upper floors. The added weight meant that the third floor gave way along with the transfer beam, which in turn caused the collapse of the building.

Arrests

Initially, the FBI had three hypotheses about responsibility for the bombing: international terrorists, possibly the same group that had carried out the World Trade Center bombing; a drug cartel, carrying out an act of vengeance against DEA agents in the building's DEA office; and anti-government radicals attempting to start a rebellion against the federal government.

McVeigh was arrested within 90 minutes of the explosion, as he was traveling north on Interstate 35 near Perry in Noble County, Oklahoma. Oklahoma State Trooper Charlie Hanger stopped McVeigh for driving his yellow 1977 Mercury Marquis without a license plate, and arrested him for having a concealed weapon. For his home address, McVeigh falsely claimed he resided at Terry Nichols's brother James's house in Michigan. After booking McVeigh into jail, Trooper Hanger searched his patrol car and found a business card which had been concealed by McVeigh after being handcuffed. Written on the back of the card, which was from a military surplus store in Antigo, Wisconsin, were the words "TNT at $5 a stick. Need more." The card was later used as evidence during McVeigh's trial.

While investigating the VIN on an axle of the truck used in the explosion and the remnants of the license plate, federal agents were able to link the truck to a specific Ryder rental agency in Junction City, Kansas. Using a sketch created with the assistance of Eldon Elliott, owner of the agency, the agents were able to implicate McVeigh in the bombing. but authorities did use a helicopter to transport him from Perry to Oklahoma City.

Federal agents obtained a warrant to search the house of McVeigh's father, Bill, after which they broke down the door and wired the house and telephone with listening devices. FBI investigators used the information gained, along with the fake address McVeigh had been using, to begin their search for the Nichols brothers, Terry and James. Investigators discovered incriminating evidence at his home: ammonium nitrate and blasting caps, the electric drill used to drill out the locks at the quarry, books on bomb-making, a copy of Hunter (a 1989 novel by William Luther Pierce, the founder and chairman of the National Alliance, a white nationalist group) and a hand-drawn map of downtown Oklahoma City, on which the Murrah Building and the spot where McVeigh's getaway car was hidden were marked. After a nine-hour interrogation, Terry Nichols was held in federal custody until his trial. On April 25, 1995, James Nichols was also arrested, but he was released after 32 days due to lack of evidence. McVeigh's sister Jennifer was accused of illegally mailing ammunition to McVeigh, but she was granted immunity in exchange for testifying against him.

A Jordanian-American man traveling from his home in Oklahoma City to visit family in Jordan on April 19, 1995, was detained and questioned by the FBI at the airport. Several Arab-American groups criticized the FBI for racial profiling, and the subsequent media coverage for publicizing the man's name. Attorney General Reno denied claims that the federal government relied on racial profiling, while FBI director Louis J. Freeh told a press conference that the man was never a suspect, and was instead treated as a "witness" to the Oklahoma City bombing, who assisted the government's investigation.

Casualties

Murrah Federal Building.

An estimated 650 people were inside the building when the bomb exploded. By the end of the day, 14 adults and six children were confirmed dead, and over 100 injured. The toll eventually reached 167 confirmed dead, not including an unmatched left leg that could have belonged to an unidentified 168th victim. Most of the deaths resulted from the collapse of the building, rather than the bomb blast itself. Those killed included 163 who were in the Alfred P. Murrah Federal Building, one person in the Athenian Building, one woman in a parking lot across the street, and a man and woman in the Oklahoma Water Resources building.

The victims ranged in age from three months to 73 years and included three pregnant women. The victims also included 19 children, of whom 15 were in the America's Kids Day Care Center. The bodies of the 168 victims were identified at a temporary morgue set up at the scene. A team of 24 identified the victims using full-body X-rays, dental examinations, fingerprinting, blood tests, and DNA testing. More than 680 people were injured.

McVeigh later acknowledged the casualties, saying, "I didn't define the rules of engagement in this conflict. The rules, if not written down, are defined by the aggressor. It was brutal, no holds barred. Women and kids were killed at Waco and Ruby Ridge. You put back in [the government's] faces exactly what they're giving out." He later stated, "I wanted the government to hurt like the people of Waco and Ruby Ridge had."

Response and relief

Rescue efforts

At 9:03 a.m., the first of over 1,800 9-1-1 calls related to the bombing were received by Emergency Medical Services Authority (EMSA). By that time, EMSA ambulances, police, and firefighters had heard the blast and were already headed to the scene. Nearby civilians, who had also witnessed or heard the blast, arrived to assist the victims and emergency workers. Immediate assistance also came from 465 members of the Oklahoma National Guard, who arrived within the hour to provide security, and from members of the Department of Civil Emergency Management.

The EMS command post was set up almost immediately following the attack and oversaw triage, treatment, transportation, and decontamination. A simple plan/objective was established: treatment and transportation of the injured was to be done as quickly as possible, supplies and personnel to handle a large number of patients was needed immediately, the dead needed to be moved to a temporary morgue until they could be transferred to the coroner's office, and measures for a long-term medical operation needed to be established. The triage center was set up near the Murrah Building and all the wounded were directed there. Two hundred and ten patients were transported from the primary triage center to nearby hospitals within the first couple of hours following the bombing. The scene had to be periodically evacuated as the police received tips claiming that other bombs had been planted in the building. although inert, it had been marked "live" in order to mislead arms traffickers in a planned law enforcement sting. The last survivor, a 15-year-old girl found under the base of the collapsed building, was rescued at around 7 p.m.

In the days following the blast, over 12,000 people participated in relief and rescue operations. The Federal Emergency Management Agency (FEMA) activated 11 of its Urban Search and Rescue Task Forces, bringing in 665 rescue workers. One nurse was killed in the rescue attempt after she was hit on the head by debris, and 26 other rescuers were hospitalized because of various injuries. Twenty-four K-9 units and out-of-state dogs were brought in to search for survivors and bodies in the building debris. For several days after the building's demolition, trucks hauled away of debris a day from the site. Some of the debris was used as evidence in the conspirators' trials, incorporated into memorials, donated to local schools, or sold to raise funds for relief efforts.

Humanitarian aid

The national humanitarian response was immediate, and in some cases even overwhelming. Large numbers of items such as wheelbarrows, bottled water, helmet lights, knee pads, rain gear, and even football helmets were donated. Local residents and those from further afield responded to the requests for blood donations. Of the over 9,000 units of blood donated, 131 were used; the rest were stored in blood banks.

Federal and state government aid

At 9:45 a.m., Governor Frank Keating declared a state of emergency and ordered all non-essential workers in the Oklahoma City area to be released from their duties for their safety.

No major federal financial assistance was made available to the survivors of the Oklahoma City bombing, but the Murrah Fund set up in the wake of the bombing attracted over $300,000 in federal grants. A committee chaired by Daniel Kurtenbach of Goodwill Industries provided temporary financial assistance of food and shelter to the survivors.

International reaction

International reactions to the bombing varied. President Clinton received many messages of sympathy, including those from Queen Elizabeth II of the United Kingdom, Yasser Arafat of the Palestine Liberation Organization, and P. V. Narasimha Rao of India. Other condolences came from Russia, Canada, Australia, the United Nations, and the European Union, among other nations and organizations.

Several countries offered to assist in both the rescue efforts and the investigation. France offered to send a special rescue unit,]]

In the wake of the bombing, the national media focused on the fact that 19 of the victims had been babies and children, many in the day-care center. At the time of the bombing, there were 100 day-care centers in the United States in 7,900 federal buildings. McVeigh later stated that he was unaware of the day-care center when choosing the building as a target, and if he had known "... it might have given me pause to switch targets. That's a large amount of collateral damage." The FBI stated that McVeigh scouted the interior of the building in December 1994 and likely knew of the day-care center before the bombing. In April 2010, Joseph Hartzler, the prosecutor at McVeigh's trial, questioned how McVeigh could have decided to pass over a prior target building because of a florist shop but at the Murrah building, not "... notice that there's a child day-care center there, that there was a credit union there and a Social Security office?"

Schools across the country were dismissed early and ordered closed. A photograph of firefighter Chris Fields emerging from the rubble with infant Baylee Almon, who later died in a nearby hospital, was reprinted worldwide and became a symbol of the attack. The photo, taken by bank employee Charles H. Porter IV, won the 1996 Pulitzer Prize for Spot News Photography and appeared on newspapers and magazines for months following the attack.

Aren Almon Kok, mother of Baylee Almon, said of the photo, "It was very hard to go to stores because they are in the check out aisle. It was always there. It was devastating. Everybody had seen my daughter dead. And that's all she became to them. She was a symbol. She was the girl in the fireman's arms. But she was a real person that got left behind."

The images and media reports of children dying terrorized many children who, as demonstrated by later research, showed symptoms of post-traumatic stress disorder. Children became a primary focus of concern in the mental health response to the bombing and many bomb-related services were delivered to the community, young and old alike. These services were delivered to public schools of Oklahoma and reached approximately 40,000 students. One of the first organized mental health activities in Oklahoma City was a clinical study of middle and high school students conducted seven weeks after the bombing. The study focused on middle and high school students who had no connection or relationship to the victims of the bombing. This study showed that these students, although deeply moved by the event and showing a sense of vulnerability on the matter, had no difficulty with the demands of school or home life, as contrasted to those who were connected to the bombing and its victims, who had post-traumatic stress disorder.

Children were also affected through the loss of parents in the bombing. Many children lost one or both parents in the blast, with seven children losing their only remaining parent. Children of the disaster have been raised by single parents, foster parents, and other family members. Adjusting to the loss has made these children suffer psychologically and emotionally. One orphan who was interviewed (of the at least ten orphaned children) reported sleepless nights and an obsession with death.

President Clinton stated that after seeing images of babies being pulled from the wreckage, he was "beyond angry" and wanted to "put [his] fist through the television". Clinton and his wife Hillary requested that aides talk to child care specialists about how to communicate with children about the bombing. Clinton said to the nation three days after the bombing, "I don't want our children to believe something terrible about life and the future and grownups in general because of this awful thing ... most adults are good people who want to protect our children in their childhood and we are going to get through this". On April 22, 1995, the Clintons spoke in the White House with over 40 federal agency employees and their children, and in a live nationwide television and radio broadcast, addressed their concerns.

Media coverage

Hundreds of news trucks and members of the press arrived at the site to cover the story. The press immediately noticed that the bombing took place on the second anniversary of the Waco incident. Hamzi Moghrabi, chairman of the American-Arab Anti-Discrimination Committee, blamed the media for harassment of Muslims and Arabs that took place after the bombing.

Those who expressed sympathy for McVeigh typically described his deed as an act of war, as in the case of Gore Vidal's essay The Meaning of Timothy McVeigh.

Aftermath

Within 48 hours of the attack, and with the assistance of the General Services Administration (GSA), the targeted federal offices were able to resume operations in other parts of the city. According to Mark Potok, director of Intelligence Project at the Southern Poverty Law Center, his organization tracked another 60 domestic smaller-scale terrorism plots from 1995 to 2005. Several of the plots were uncovered and prevented while others caused various infrastructure damage, deaths, or other destruction. Potok revealed that in 1996 there were approximately 858 domestic militias and other antigovernment groups but the number had dropped to 152 by 2004. Shortly after the bombing, the FBI hired an additional 500 agents to investigate potential domestic terrorist attacks. A 2005 Federal Bureau of Investigation report said the bombing "brought the threat of right-wing terrorism to the forefront of American law enforcement attention."

Legislation

In the wake of the bombing, the U.S. government enacted several pieces of legislation including the Antiterrorism and Effective Death Penalty Act of 1996. In response to the trials of the conspirators being moved out-of-state, the Victim Allocution Clarification Act of 1997 was signed on March 20, 1997, by President Clinton to allow the victims of the bombing (and the victims of any other future acts of violence) the right to observe trials and to offer impact testimony in sentencing hearings. Clinton stated that "when someone is a victim, he or she should be at the center of the criminal justice process, not on the outside looking in."

In the years since the bombing, scientists, security experts, and the ATF have called on Congress to develop legislation that would require customers to produce identification when purchasing ammonium nitrate fertilizer, and for sellers to maintain records of its sale. Critics argue that farmers lawfully use large quantities of the fertilizer, and as of 2009, only Nevada and South Carolina require identification from purchasers. In 2008, Honeywell announced that it had developed a nitrogen-based fertilizer that would not detonate when mixed with fuel oil. The company got assistance from the Department of Homeland Security to develop the fertilizer (Sulf-N 26) for commercial use. It uses ammonium sulfate to make the fertilizer less explosive.

Oklahoma school curriculum

In the decade following the bombing, there was criticism of Oklahoma public schools for not requiring the bombing to be covered in the curriculum of Oklahoma history classes. Oklahoma History is a one-semester course required by state law for graduation from high school, but the bombing was only covered for one to two pages at most in textbooks. The state's PASS standards (Priority Academic Student Skills) did not require that a student learn about the bombing. On April 6, 2010, House Bill 2750 was signed by Governor Brad Henry, requiring the bombing to be entered into the school curriculum for Oklahoma, U.S. and world history classes.

On the signing, Governor Henry said, <blockquote>Although the events of April 19, 1995, may be etched in our minds and in the minds of Oklahomans who remember that day, we have a generation of Oklahomans that has little to no memory of the events of that day ... We owe it to the victims, the survivors and all of the people touched by this tragic event to remember April 19, 1995, and understand what it meant and still means to this state and this nation. As part of a longer-term plan for United States federal building security, most of those temporary barriers have since been replaced with permanent and more aesthetically considerate security barriers, which are driven deep into the ground for sturdiness. All new federal buildings must now be constructed with truck-resistant barriers and with deep setbacks from surrounding streets to minimize their vulnerability to truck bombs. FBI buildings, for instance, must be set back from traffic. The total cost of improving security in federal buildings across the country in response to the bombing reached over $600 million.

The Murrah Federal Building had been considered so safe that it only employed one security guard. In June 1995, the DOJ issued Vulnerability Assessment of Federal Facilities, also known as The Marshals Report, the findings of which resulted in a thorough evaluation of security at all federal buildings and a system for classifying risks at over 1,300 federal facilities owned or leased by the federal government. Federal sites were divided into five security levels ranging from Level 1 (minimum security needs) to Level 5 (maximum). The Alfred P. Murrah Building was deemed a Level 4 building. Among the 52 security improvements were physical barriers, closed-circuit television monitoring, site planning and access, hardening of building exteriors to increase blast resistance, glazing systems to reduce flying glass shards and fatalities, and structural engineering design to prevent progressive collapse.

The attack led to engineering improvements allowing buildings to better withstand tremendous forces, improvements which were incorporated into the design of Oklahoma City's new federal building. The National Geographic Channel documentary series Seconds From Disaster suggested that the Murrah Federal Building would probably have survived the blast had it been built according to California's earthquake design codes.

Drag racing

The National Hot Rod Association has tightened its regulations for nitromethane. Section 21 of the current NHRA rule book states nitromethane is limited to , or in a barrel, instead of the normal . The NHRA requires competitors to submit a Top Screen Questionnaire to the Department of Homeland Security. In addition, competitors are not allowed to own nitromethane at official events. Instead, it must be stored at the series' official fuel supplier, VP Racing Fuel (as of 2025). Each time a team purchases nitromethane, it is logged by the Series fuel supplier, which dispenses the correct amount of nitromethane ordered to the specific team.

Impact according to McVeigh

McVeigh believed that the bomb attack had a positive impact on government policy. In evidence he cited the peaceful resolution of the Montana Freemen standoff in 1996, the government's $3.1 million settlement with Randy Weaver and his surviving children four months after the bombing, and April 2000 statements by Bill Clinton regretting his decision to storm the Branch Davidian compound. McVeigh stated, "Once you bloody the bully's nose, and he knows he's going to be punched again, he's not coming back around."

Evacuation issues

Several agencies, including the Federal Highway Administration and the City of Oklahoma City, have evaluated the emergency response actions to the bombing and have proposed plans for a better response in addition to addressing issues that hindered a smooth rescue effort. Because of the crowded streets and the number of response agencies sent to the location, communication between government branches and rescue workers was muddled. Groups were unaware of the operations others were conducting, thus creating strife and delays in the search and rescue process. The City of Oklahoma City, in their After Action Report,

The Federal Bureau of Investigation (FBI) led the official investigation, known as OKBOMB, with Weldon L. Kennedy acting as special agent in charge. Kennedy oversaw 900 federal, state, and local law enforcement personnel, including 300 FBI agents, 200 officers from the Oklahoma City Police Department, 125 members of the Oklahoma National Guard, and 55 officers from the Oklahoma Department of Public Safety. The crime task force was deemed the largest since the investigation into the assassination of John F. Kennedy. OKBOMB was the largest criminal case in America's history, with FBI agents conducting 28,000 interviews, amassing of evidence, and collecting nearly one billion pieces of information. Federal judge Richard Paul Matsch ordered that the venue for the trial be moved from Oklahoma City to Denver, Colorado, ruling that the defendants would be unable to receive a fair trial in Oklahoma. The investigation led to the separate trials and convictions of McVeigh, Nichols and Fortier.

McVeigh

Opening statements in McVeigh's trial began on April 24, 1997. The United States was represented by a team of prosecutors led by Joseph Hartzler. In his opening statement Hartzler outlined McVeigh's motivations, and the evidence against him. McVeigh, he said, had developed a hatred of the government during his time in the army, after reading The Turner Diaries. His beliefs were supported by what he saw as the militia's ideological opposition to increases in taxes and the passage of the Brady Bill, and were further reinforced by the Waco and Ruby Ridge incidents. The prosecution called 137 witnesses, including Michael Fortier and his wife Lori, and McVeigh's sister, Jennifer McVeigh, all of whom testified to confirm McVeigh's hatred of the government and his desire to take militant action against it. Both Fortiers testified that McVeigh had told them of his plans to bomb the Alfred P. Murrah Federal Building. Michael Fortier revealed that McVeigh had chosen the date, and Lori Fortier testified that she had created the false identification card McVeigh used to rent the Ryder truck.

McVeigh was represented by a team of six principal attorneys, led by Stephen Jones. According to law professor Douglas O. Linder, McVeigh wanted Jones to present a "necessity defense"—which would argue that he was in "imminent danger" from the government (that his bombing was intended to prevent future crimes by the government, such as the Waco and Ruby Ridge incidents).

Numerous damaging leaks, which appeared to originate from conversations between McVeigh and his defense attorneys, emerged. They included a confession said to have been inadvertently included on a computer disk that was given to the press, which McVeigh believed seriously compromised his chances of getting a fair trial. Although the defense argued for a reduced sentence of life imprisonment, McVeigh was sentenced to death. In May 2001, the Justice Department announced that the FBI had mistakenly failed to provide over 3,000 documents to McVeigh's defense counsel. The Justice Department also announced that the execution would be postponed for one month for the defense to review the documents. On June 6, federal judge Richard Paul Matsch ruled the documents would not prove McVeigh innocent and ordered the execution to proceed. McVeigh invited conductor David Woodard to perform pre-requiem Mass music on the eve of his execution; while reproachful of McVeigh's capital wrongdoing, Woodard consented. After President George W. Bush approved the execution (McVeigh was a federal inmate and federal law dictates that the president must approve the execution of federal prisoners), he was executed by lethal injection at the Federal Correctional Complex, Terre Haute in Terre Haute, Indiana, on June 11, 2001. The execution was transmitted on closed-circuit television so that the relatives of the victims could witness his death. McVeigh's execution was the first federal execution in 38 years.

Nichols

Nichols stood trial twice. He was first tried by the federal government in 1997, and found guilty of conspiring to build a weapon of mass destruction and of eight counts of involuntary manslaughter of federal officers. After he was sentenced on June 4, 1998, to life without parole, the State of Oklahoma in 2000 sought a death-penalty conviction on 161 counts of first-degree murder (160 non-federal-agent victims and one fetus). On May 26, 2004, the jury found him guilty on all charges, but deadlocked on the issue of sentencing him to death. Presiding Judge Steven W. Taylor then determined the sentence of 161 consecutive life terms without the possibility of parole. In March 2005, FBI investigators, acting on a tip from Gregory Scarpa Jr., searched a buried crawl space in Nichols's former house, and found additional explosives missed in the preliminary search after Nichols was arrested.

Michael and Lori Fortier

Michael and Lori Fortier were considered accomplices for their foreknowledge of the planning of the bombing. In addition to Michael's assisting McVeigh in scouting the federal building, Lori had helped McVeigh laminate the fake driver's license that was later used to rent the Ryder truck. He was sentenced on May 27, 1998, to 12 years in prison, and fined $75,000 for failing to warn authorities about the attack. On January 20, 2006, Michael was released from prison, transferred into the Witness Protection Program, and given a new identity.

Conspiracy theories

Several conspiracy theories have been proposed regarding the bombing in 1995. These theories reject all, or part of, the official government report. Some of these theories focus on the possibility of additional co-conspirators alongside Timothy McVeigh and Terry Nichols that were never indicted or additional explosives planted inside the Alfred P. Murrah Federal Building.

No "John Doe #2" was ever identified, and the government never openly investigated anyone else in conjunction with the bombing. Although the defense teams in both McVeigh's and Nichols's trials suggested that others were involved, Judge Steven W. Taylor found no credible, relevant, or legally admissible evidence of anyone other than McVeigh and Nichols having directly participated in the bombing. On the morning of McVeigh's execution a letter was released in which he had written "For those die-hard conspiracy theorists who will refuse to believe this, I turn the tables and say: Show me where I needed anyone else. Financing? Logistics? Specialized tech skills? Brainpower? Strategy? ... Show me where I needed a dark, mysterious 'Mr. X'!"

Memorial observances

Oklahoma City National Memorial

For two years after the bombing the only memorials to the victims were plush toys, crucifixes, letters, and other personal items left by thousands of people at a security fence surrounding the site of the building. Many suggestions for suitable memorials were sent to Oklahoma City, but an official memorial planning committee was not set up until early 1996, when the Murrah Federal Building Memorial Task Force, composed of 350 members, was set up to formulate plans for a memorial to commemorate the victims of the bombing. The memorial was designed at a cost of $29 million, which was raised by public and private funds. The national memorial is part of the National Park System as an affiliated area and was designed by Oklahoma City architects Hans and Torrey Butzer and Sven Berg. Within the first year, it had 700,000 visitors. North of the memorial is the Journal Record Building, which now houses the Oklahoma City National Memorial Museum, an affiliate of the National Park Service. The building also contained the National Memorial Institute for the Prevention of Terrorism, a law enforcement training center.

St. Joseph's Old Cathedral

St. Joseph's Old Cathedral, one of the first brick-and-mortar churches in the city, is located to the southwest of the memorial and was severely damaged by the blast. To commemorate the event, a statue and sculpture work entitled And Jesus Wept was installed adjacent to the Oklahoma City National Memorial. The work was dedicated in May 1997 and the church was rededicated on December 1 of the same year. The church, the statue, and the sculpture are not part of the Oklahoma City memorial.

Remembrance observance

An observance is held each year to remember the victims of the bombing. An annual marathon draws thousands, and allows runners to sponsor a victim of the bombing. For the tenth anniversary of the bombing, the city held 24 days of activities, including a week-long series of events known as the National Week of Hope from April 17 to 24, 2005. As in previous years, the tenth anniversary of the bombing observances began with a service at 9:02 a.m., marking the moment the bomb went off, with the traditional 168 seconds of silence—one second for each person who was killed. The service also included the traditional reading of the names, read by children to symbolize the future of Oklahoma City.

Vice President Dick Cheney, former President Clinton, Oklahoma Governor Brad Henry, Frank Keating, Governor of Oklahoma at the time of the bombing, and other political dignitaries attended the service and gave speeches in which they emphasized that "goodness overcame evil". The relatives of the victims and the survivors of the blast also made note of it during the service at First United Methodist Church in Oklahoma City. President George W. Bush issued a written statement, part of which echoed his remarks on the execution of Timothy McVeigh in 2001: "For the survivors of the crime and for the families of the dead the pain goes on."

Due to the COVID-19 pandemic, the memorial site was closed to the public and local television networks broadcast pre-recorded remembrances to mark the 25th anniversary.
