A congressional ban on CDC research of gun violence actually was lifted by an executive order from President Barack Obama in early 2013, after the massacre of 20 children and six adults in Sandy Hook Elementary School in Newtown, Connecticut. But Congress has since blocked funding for such research.
Stack said that "an epidemiological analysis of gun violence is vital so physicians and other health providers, law enforcement and society at large may be able to prevent injury, death and other harms to society resulting from firearms."
The AMA noted it has "numerous, long-standing policies that support increasing the safety of firearms and their use, and reducing and preventing firearm violence."
The group said it "recognizes that uncontrolled ownership and use of firearms, especially handguns, is a serious threat to the public's health inasmuch as the weapons are one of the main causes of intentional and unintentional injuries and deaths." The AMA has also supported legislation calling for a waiting period before purchasing any form of firearm in the U.S. and requiring background checks for all handgun purchasers.
Correction: An earlier version of this story incorrectly identified the type of rifle used in the Orlando mass shooting.
