Waco, the Big Lie is a 1993 American documentary film directed by Linda Thompson that presents video based analysis regarding the Waco siege.
 The first film made about the Waco siege, "Waco, the Big Lie" gained significant notoriety when it was viewed during the trial of American domestic terrorist Timothy McVeigh.
 As part of the defense, McVeigh's lawyers showed "Waco, the Big Lie" to the jury.
Terry Lynn Nichols (born April 1, 1955) is an American who was convicted of being an accomplice in the Oklahoma City bombing.
 Prior to his incarceration, he held a variety of short-term jobs, working as a farmer, grain elevator manager, real estate salesman and ranch hand.
 He met his future conspirator, Timothy McVeigh, during a brief stint in the U.S. Army, which ended in 1989 when he requested a hardship discharge after less than one year of service.
 In 1994 and 1995, he conspired with McVeigh in the planning and preparation of the Oklahoma City bombing – the truck bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, on April 19, 1995.
 The bombing claimed the lives of 168 people.
David Paul Hammer (born October 9, 1958) is an American murderer.
 He has been recently transferred from the federal death row at Terre Haute prison, Indiana to United States Penitentiary, Canaan.
 He was sentenced to death on November 4, 1998 for the murder of his cell mate, Andrew Marti.
 Hammer has achieved media fame for his appeals against his sentence and against the death penalty itself, and for his statements and books about the 1995 Oklahoma City bombing based on information he allegedly obtained from convicted bomber Timothy McVeigh.
American Terrorist: Timothy McVeigh & The Oklahoma City Bombing (2001) is a book by Buffalo, New York journalists Lou Michel and Dan Herbeck that chronicles the life of Timothy McVeigh from his childhood in Pendleton, New York, to his military experiences in the Persian Gulf War, to his preparations for and carrying out of the Oklahoma City bombing, to his trial and death row experience.
 One of the appendices lists all 168 people killed in the blast, along with brief biographical information.
 (There were plans to include a chapter about his execution in the softcover edition.)
 It is the only biography authorized by McVeigh himself, and was based on 75 hours of interviews that the authors had with McVeigh.
 McVeigh was said to be pleased overall with the book, but disappointed with the way he was portrayed and the explanation of his motive.
 Coauthor Michel said he viewed McVeigh as a "human being with a limited range of feelings in the areas of empathy and sympathy and with an oversized sense of rage and resentment."
The Aryan Republican Army is the name given to white supremacist criminal group active in the United States in the early to mid-1990s.
 The group is alleged to have associated with convicted bomber Timothy McVeigh in the months before the Oklahoma City bombing.
 The organization was sometimes referenced in the media as the Midwest Bank Robbers.
 The group was created by Peter Langan and Richard Lee Guthrie in 1992.
 The group considered themselves a leaderless organization, meaning that there was no true leader to the group and that they were more of a group of associated people acting together to achieve their goals.
 Although the group was mainly a criminal enterprise, they did have a terrorist like agenda.
 With the money they were able to steal in the 22 confirmed robberies they were involved in, the group began stockpiling weapons and ammunition.
 It is believed that the group wished to start a race war with the weapons that were stockpiled.
 The group began to fall apart as members of the Aryan Republican Army were arrested after one of the former members of the group became an informant as part of a plea bargain.
 By mid-1996, practically all known members had been apprehended and the group was in shambles.
Elohim City is a private community in Adair County, Oklahoma.
 The 400 acre rural retreat was founded in 1973 by Robert G. Millar (August 16, 1925 - May 28, 2001), a Canadian immigrant, former Mennonite and important leader in America's Christian Identity movement, a theology common to an assortment of right-wing extremist groups.
 The community gained national attention for its alleged ties to members of The Order in the 1980s and with convicted Oklahoma City bomber Timothy McVeigh in the 1990s.
The Alfred P. Murrah Federal Building was a United States federal government complex located at 200 N.W. 5th Street in Downtown Oklahoma City, Oklahoma, United States.
 It was the target of the Oklahoma City bombing on April 19, 1995 at 9:02am, which killed 168 people, 19 of whom were children under the age of six.
 Half of the building collapsed seconds after the truck bomb detonated.
 The remains were imploded a month after the attack, and the Oklahoma City National Memorial was built on the site.
The Oklahoma City bombing was a domestic terrorist truck bombing on the Alfred P. Murrah Federal Building in downtown Oklahoma City, Oklahoma, United States on April 19, 1995.
 Perpetrated by Timothy McVeigh and Terry Nichols, the bombing killed 168 people, injured more than 680 others, and destroyed one-third of the building.
 The blast destroyed or damaged 324 other buildings within a 16-block radius, shattered glass in 258 nearby buildings, and destroyed or burned 86 cars, causing an estimated $652 million worth of damage.
 Extensive rescue efforts were undertaken by local, state, federal, and worldwide agencies in the wake of the bombing, and substantial donations were received from across the country.
 The Federal Emergency Management Agency (FEMA) activated eleven of its Urban Search and Rescue Task Forces, consisting of 665 rescue workers who assisted in rescue and recovery operations.
 The Oklahoma City bombing was the deadliest terrorist attack on American soil until the September 11 attacks six years later, and it still remains the deadliest incident of domestic terrorism in United States history.
Timothy James McVeigh (April 23, 1968 – June 11, 2001) was an American domestic terrorist convicted and executed for the detonation of an ammonium nitrate fertilizer and nitromethane truck bomb in front of the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995.
 Commonly referred to as the Oklahoma City bombing, the attack killed 168 people and injured over 600.
 According to the United States government, it was the deadliest act of terrorism within the United States prior to the September 11 attacks, and remains the most significant act of domestic terrorism in United States history.
Victor Harry Feguer (1935 – March 15, 1963) was a convicted murderer and the last federal inmate executed in the United States before the moratorium on the death penalty following "Furman v. Georgia", and the last person put to death in the state of Iowa.
 While at the time the news media paid little attention to Victor Feguer or his execution, Timothy McVeigh's execution sparked renewed media interest in Feguer.
