Shoot First laws in the United States lead to substantial increases in violence
and the senseless loss of hundreds of lives every year.
Research shows that these laws have increased gun homicides by up to 11 percent nationally,
translating to more than 700 deaths annually.
Some Shoot First states have seen even steeper increases, with those rates rising by 30 percent or more in Alabama, Florida, and Missouri.
Adolescents experience higher rates of gun homicides under Shoot First laws.
And though many people associate gun homicides and assaults with cities, research shows that Shoot First laws do not discriminate, increasing violence in suburban and urban counties as well as among white and Black populations
