Due to the political impact, this has spurred some to press for more stringent [[gun control]] laws. In the United States, the National Rifle Association is opposed to such laws, and some groups have called for fewer gun control laws, citing cases of armed students ending shootings and halting further loss of life, and claiming that the prohibitions against carrying a gun in schools do not deter the gunmen.<ref name="lab1">{{cite web |first=Eric |last=Puryear |url=http://www.learnaboutguns.com/2008/04/30/the-flawed-reasoning-behind-gun-free-zones/ |title=A discussion of the reasoning behind gun free zone, 2007–2008 |date=April 30, 2008 |access-date=May 4, 2012}}</ref>{{better source needed|reason=pro-gun website is source, not objective.|date=December 2012}}<ref>{{cite web|url=http://www.bmsg.org/resources/publications/issue-8-the-debate-on-gun-policies-in-US-and-midwest-newspapers|title=Issue 8: The debate on gun policies in U.S. and midwest newspapers – Berkeley Media Studies Group|website=Bmsg.org}}</ref> One such example is the [[Mercaz HaRav Massacre]], where the attacker was stopped by a student, Yitzhak Dadon, who shot him with his personal firearm which he lawfully carried concealed.

[[Gun-Free Schools Act of 1994|The Gun-Free Schools Act]] was passed in 1994 in response to gun related violence in schools, so many school systems started adopting the Zero-Tolerance Law. The Gun-Free Schools Act required people to be expelled from the school for a year. By 1997, the Zero-Tolerance for any type of weapon was implemented by more than 90 percent of U.S. public schools.<ref>{{cite journal|url=http://library.cqpress.com/cqresearcher/document.php?id=cqresrre2000031000&type=hitlist&num=0#.UnxPbvmshcY|title=Zero Tolerance for School Violence|journal=CQ Researcher by CQ Press|date=March 10, 2000 |volume=10 |issue=9 |pages=185–208 |access-date=May 22, 2018 |last1=Koch |first1=Kathy }}</ref>
