Mass shootings that involve large-capacity gun magazines are significantly more deadly than those that do not, according to a brief by the non-profit Citizens Crime Commission of New York City.
The Commission's “Mass Shooting Incidents in America” database catalogs shootings since 1984 that resulted in more than four deaths.
Mass shootings were dramatically less deadly between 1994 and 2004, when the federal Assault Weapons Ban was in effect, according to the commission.
“The number of people killed or injured in mass shootings during the decade of the ban was half what it was in the decade before (119 v. 241),” researchers wrote. “And it was a third of the number of casualties since (329 from September 2004 through 2012).”
Overall, shooters who used large-capacity magazines between 1984 and 2012 killed or injured 161 percent more people than those who did not, according to the study.
“There were nearly 700 victims in those incidents—78% more killed than when a regular-capacity magazine was used, and 319% more injured,” researchers wrote.
