{{Terrorism}}

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]].<ref name="AntiFAS" /> 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. In response to passing the legislation, 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."<ref name="Barbarians">{{cite journal|last=Cassell|first=Paul|title=Barbarians at the Gates?

In the years since the bombing, scientists, security experts, and the [[Bureau of Alcohol, Tobacco, Firearms and Explosives|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,<ref name="ANLegislate">{{cite news|last=Condon |first=Patrick |title=Bomb ingredient restricted in 2 states |date=June 12, 2004 |work=[[The Boston Globe]] |url=https://www.boston.com/news/nation/articles/2004/06/12/bomb_ingredient_restricted_in_2_states_fertilizer_mostly_goes_untracked/ |archive-url=https://web.archive.org/web/20120725111152/http://www.boston.com/news/nation/articles/2004/06/12/bomb_ingredient_restricted_in_2_states_fertilizer_mostly_goes_untracked/ |archive-date=July 25, 2012 |url-status=dead}}</ref> and as of 2009, only Nevada and South Carolina require identification from purchasers.<ref name="ANLegislate"/> In June 1995, Congress enacted legislation requiring chemical [[taggant]]s to be incorporated into dynamite and other explosives so that a bomb could be traced to its manufacturer.<ref name="Taggants">{{cite news|last=Gray |first=Jerry |title=Senate Votes to Aid Tracing of Explosives |date=June 6, 1995 |work=[[The New York Times]] |url=https://www.nytimes.com/1995/06/06/us/senate-votes-to-aid-tracing-of-explosives.html |archive-url=https://web.archive.org/web/20130605150702/http://www.nytimes.com/1995/06/06/us/senate-votes-to-aid-tracing-of-explosives.html |archive-date=June 5, 2013 |url-status=dead}}</ref> In 2008, [[Honeywell]] announced that it had developed a nitrogen-based fertilizer that would not detonate when mixed with fuel oil.
