Banning the AR-15 should not be a partisan issue. While there may be no consensus on many questions of gun control, there seems to be broad support for removing high-velocity, lethal weaponry and high-capacity magazines from the market, which would drastically reduce the incidence of mass murders. Every constitutionally guaranteed right that we are blessed to enjoy comes with responsibilities. Even our right to free speech is not limitless. Second Amendment gun rights must respect the same boundaries. 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 This provision needs to be repealed so that the CDC can study this issue and make sensible gun-policy recommendations to Congress.
