In light of the difficulty achieving consensus about gun violence prevention at the federal level in the current political climate, leadership and innovation on gun violence prevention must come at the state and local levels. State legislators, law enforcement leaders, and state attorneys general must take the lead to find the pathway that most effectively protects their residents in collaboration with concerned communities. There is substantial evidence that states with comprehensive and effective gun laws have fewer incidents of gun homicides, gun suicides, and unintentional shooting deaths. These 50 proposals for state or local action have demonstrated success where they have been enacted and are a starting point for states interested in promoting public safety by addressing preventable gun violence.

Large capacity ammunition magazines are the common thread running through most mass shootings in the United States. Since 1980, there have been at least 106 mass shootings (three or more fatalities not including the shooter) where the shooter used large capacity ammunition magazines containing more than 10 rounds. A total of 959 people were killed in these shootings, and 1,309 were wounded. This number is likely a significant undercount of actual incidents as there is no consistent collection or reporting on this data. Even in many high-profile shootings, information on magazine capacity is neither released nor reported. The Violence Policy Center has compiled this list of incidents by analyzing news reports and follow-up investigative reports on mass shootings. Only shootings in which there is specific information that large capacity magazines were used are included.  ( This document was last updated on January 11, 2024.

When one thinks of arms traffickers, the image that often comes to mind is of the stereotypical ‘Merchant of Death’ – ambitious, well-connected, globetrotting entrepreneurs who single-handedly arm warlords and insurgents across the world. While there is some truth to the stereotype, most illicit arms traffickers do not fit this profile. The latest Issue Brief from the Small Arms Survey—Dribs and Drabs: The Mechanics of Small Arms Trafficking from the United States—analyses a side of the arms trade that is less flashy, less centralized, and even more difficult to stop. Using an extensive database compiled from court records, the Issue Brief looks at the modes of transport, concealment methods, and smuggling techniques employed by arms traffickers in the United States, most of whom bear little resemblance to the ‘Merchants of Death’.

This Issue Brief draws on a database that follows the activities of more than 400 individuals accused of illegally shipping small arms and light weapons, their parts, accessories, or ammunition from the US to at least 46 countries. It offers an overview of the types of small arms trafficked and how smugglers evade export controls and border controls. The Brief concludes with a policy-relevant analysis of the implications of these cases.

With rising suicide rates in the U.S., Anestis provides a much-needed understanding of suicide prevention and the critical role of means restriction shifts the conversation about gun violence to suicides by guns, which make up the majority of gun deaths in the U.S. Anestis takes a poignant, balanced approach to reducing suicide risk; this is not a book about gun control. Masterfully describes scientific evidence and data in accessible prose that will appeal to a large audience interested in issues related to suicide and gun violence

Congress has debated the efficacy and constitutionality of federal regulation of firearms and ammunition, with strong advocates arguing for and against greater gun control. In the wake of the July 20, 2012, Aurora, CO, theater mass shooting, in which 12 people were shot to death and 58 wounded (7 of them critically) by a lone gunman, it is likely that there will be calls in the 112th Congress to reconsider a 1994 ban on semiautomatic assault weapons and large capacity ammunition feeding devices that expired in September 2004. There were similar calls to ban such feeding devices (see S. 436/H.R. 1781) following the January 8, 2011, Tucson, AZ, mass shooting, in which 6 people were killed and 14 wounded, including Representative Gabrielle Giffords, who was grievously wounded. These calls could be amplified by the August 5, 2012, Sikh temple shooting in Milwaukee, WI, in which six worshipers were shot to death and three wounded by a lone gunman. The 112th Congress continues to consider the implications of Operation Fast and Furious and allegations that the Department of Justice (DOJ) and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) mishandled that Phoenix, AZ-based gun trafficking investigation. On June 28, 2012, the House passed a resolution (H.Res. 711) citing Attorney General Eric Holder with contempt for his failure to produce additional, subpoenaed documents related to Operation Fast and Furious to the Committee on Oversight and Government Reform. On May 18, 2012, the House passed the National Defense Authorization Act (NDAA) for Fiscal Year 2013 (H.R. 4310), which would amend a limitation on the Secretary of Defense’s authority to regulate firearms privately held by members of the Armed Forces off-base. On May 10, 2012, the House passed a Commerce-Justice-State appropriations bill (H.R. 5326) that would fund ATF for FY2013, and on April 19, 2012, the Senate Committee on Appropriations reported a similar bill (S. 2323)

The Commission conducted 15 meetings open to members of the public. The Commission received statements from an extensive list of State and local officials and private persons who had experience with or information concerning the event; Commission staff reviewed thousands of pages of official and unofficial documents, reports, and studies. Two recommendations related to crisis response actions. First, law enforcement policy and training should emphasize that the highest priority of law enforcement officers, after arriving at the scene of a crisis, is to stop any ongoing assault. Second, there should be an increased emphasis on training appropriate personnel in preparation for and responding to large-scale emergencies. Two recommendations pertained to improved communications for critical emergencies. First, law enforcement agencies should plan their communications systems to facilitate crisis communication with other agencies with whom they might reasonably be expected to interface in emergencies. Second, Colorado should continue to develop a single statewide digital trunked communications system. Other categories of recommendations pertained to advance planning for critical emergencies; interaction with media representatives; tasks of school resource officers; detection by school administrators of potential perpetrators of school-based violence and administrative countermeasures; medical treatment for attack victims; reuniting attack victims and their families; identification of victims' bodies and family access to bodies; and suicide prevention in the aftermath of traumatic incidents.
