– In a November 2017 review of mass shootings in the U.S., 95 mass shootings have occurred since 1982, from which approximately 76 semi-automatic handguns and 85 assault weapons and weapons with high magazine capacity were recovered.
– In 2017 alone, 11 mass shootings in the US caused 117 fatalities and 587 injuries occuring in concert, religious, workplace, airport, and shopping venues and in community.
– States that restrict assault weapons also have the lowest per capita homicide rates.
– Researchers from Harvard School of Public Health demonstrated that from 1982 to 2011, mass shootings occurred every 200 days on average. Since late 2011, they found, mass shootings have occurred at triple that rate—every 64 days on average.
– Federal legislation passed in 1997 stated that “none of the funds made available for injury prevention and control at the Centers for Disease Control and Prevention (CDC) may be used to advocate or promote gun control.” The vague nature of this law, and its 2011 extension to the National Institutes of Health, has effectively prevented federal funding for firearms-related research.
– In 2013, following the Sandy Hook shooting, former President Barack Obama issued an executive order calling for the CDC to “conduct or sponsor research into the causes of gun violence and the ways to prevent it”. Despite this and without specific appropriations from U.S. Congress, new research proposals remain unfunded.
