The Federal Assault Weapons Ban (AWB) of 1994 included language which prohibited semi-automatic rifles like the AR-15, and also large-capacity magazines with the ability to hold more than 10 rounds. The ban was allowed to expire after 10 years on September 13, 2004. The mass murders that followed the ban’s lapse make clear that it must be reinstated.
On Wednesday night, Rubio said at a town-hall event hosted by CNN that it is impossible to create effective gun regulations because there are too many “loopholes” and that a “plastic grip” can make the difference between a gun that is legal and illegal. But if we can see the different impacts of high- and low-velocity rounds clinically, then the government can also draw such distinctions.
The CDC is the appropriate agency to review the potential impact of banning AR-15 style rifles and high-capacity magazines on the incidence of mass shootings. The agency was effectively barred from studying gun violence as a public-health issue in 1996 by a statutory provision known as the Dickey amendment. This provision needs to be repealed so that the CDC can study this issue and make sensible gun-policy recommendations to Congress.
