This guide by Mother Jones has been updated numerous times to include information on recurring mass shooting that involved the murder of Americans in houses of worship, schools, work places, and public places.  Please note, the majority of weapons used in these murders were purchased legally and ..”More than half of the cases involved school or workplace shootings.”

“Weapons: Of the 143 guns possessed by the killers, more than three quarters were obtained legally. The arsenal included dozens of assault weapons and semi-automatic handguns with high-capacity magazines.”

• Private Guns, Public Health by David Hemenway – The first complete picture of the public-health approach to gun violence, and a commonsense plan for ending this American epidemic: “On an average day in the United States, guns are used to kill almost eighty people, and to wound nearly three hundred more. If any other consumer product had this sort of disastrous effect, the public outcry would be deafening; yet when it comes to guns such facts are accepted as a natural consequence of supposedly high American rates of violence.”
