Firearms are the second leading cause of injury and deaths in the United States accounting for 30,896 deaths and 71,417 injuries in 2006. Over 80 percent of teen homicides and almost half of teen suicides in involved a gun in 2005. CDC: WISQUARS. Overall, more than half of all homicides involve a gun. US Department of Justice: Crime Statistics.
The federal government, through the Interim Brady Handgun Violence Prevention Act, in place from 1993 to 1998, established a five-day waiting period for the purchase of a firearm. In 1998, the Brady Handgun Violence Prevention Act (18 U.S.C. §921-922) updated the Interim Brady Law, replacing the five day waiting period and the mandatory background check conducted by law enforcement officials with an instant computerized background check that typically takes a few seconds (but may take up to three days). Some states have implemented longer waiting periods; for example, California’s waiting period is 10 days (Cal. Penal Code §§ 12071(b)(3)(A), 12072(c)(1)) and New York’s waiting period can be up to six months (NY PEN § 400.00(4-a)). The aim of waiting periods is to allow time to complete background checks on the purchaser and to provide time for individuals with impulsive violent intentions to “cool off.”
Hahn et al. reviewed seven studies that measured the effects of waiting periods on murder, aggravated assault, robbery, rape, firearm-related suicide, and unintentional firearm injury. Hahn, et al. Firearms laws and the reduction of violence: a systemic review. Am J Prev Med. 2005;28(2S1):40-71. The reviewers found the underlying studies to have a number of methodological limitations. The findings of the underlying studies were inconsistent and or statistically insignificant. For there reasons, the reviewers were unable to determine the effectiveness of waiting periods laws as interventions aimed at reducing gun-related harms.

A new firearms research database launched by the Harvard School of Public Health makes scholarly articles more accessible to reporters, law enforcement, public health officials, policymakers, and the general public. The Firearms Research Digest provides summaries of articles gathered from social science, criminology, medical and public health journals and is written in clear, accessible language for use by those outside academia.
The website currently covers six years of research published between 2003 and 2008. The digest will be expanded over time to include articles from 1988 to the present.

Firearms are the second leading cause of injury deaths in the United States accounting for 30,896 deaths and 71,417 injuries in 2006. CDC: WISQUARS. Annually, firearm injuries generate life-time medical costs of roughly $2.3 billion. Cook PJ, Lawrence BA, Ludwig J, Miller TR. The medical costs of gunshot injuries in the United States. JAMA. 1999;282:447-454.
State and local legislators have sought to reduce the use and illegal possession of firearms by implementing firearm registration and licensing requirements. Firearm registration requires that a record of firearm ownership be kept. Firearm licensing requires individuals to obtain government authorization before purchasing a firearm. For examples of state gun registration laws, see ARS § 13-3101 (Arizona) and N.Y. PEN § 400.00 (New York). For examples of state licensing laws, see 430 ILCS 65 (Illinois) and MGL c.140, § 131, 131 F (Massachusetts).
Hahn et al. reviewed five studies that measured the impact of licensing laws and or registration laws on violent outcomes. Hahn, et al. Firearms laws and the reduction of violence: a systemic review. Am J Prev Med. 2005;28(2S1):40-71. The review defined violent outcomes as specific violent crimes (all murder, aggravated assault, robbery, and rape), firearm-related suicide, and unintentional firearm injury. Due to inconsistent and statistically insignificant findings in the limited underlying studies, the reviewers concluded that there is currently not enough evidence to determine the effectiveness of registration and licensing requirements as public health interventions aimed at reducing gun-related harms.
