Guns: NRA has stopped research on Gun Deaths and Killings for many years.

Follow the money: "I think that the NRA exists to help sell more guns," Mark Rosenberg, who became the first director of the NCIPC in 1994 and served until 1999, told Mic in a phone interview. "I think that the leadership of the NRA saw what some of our early research was showing. The NRA wanted people to feel that the best way to protect your family in your home was to have a gun. And they thought that was a good way to sell guns."

"They decided they needed to shut this research down," he said.

Shut it down they did. Over the last 40 years, MSNBC reports the NIH funded just three studies on gun violence, while the CDC now "asks researchers to let it know any time they're publishing something on firearms — then gives the NRA a heads up."

"They're the ones who have exactly the resources that are needed," Elliot Fineman, founder of the National Gun Victims Action Council, told Mic in a phone interview. "We're living under a gun violence epidemic. We all know that. Think of the response they have when they find out cans of tomato soup are poisoning people. They recall millions of cans of tomato soup. The full mechanisms of the government come into play."

"In a nation dedicated to personal freedom and responsibility, it is ironic that policymakers and the public have been denied access to timely and objective research on this issue for 15 years and counting," researcher Arthur Kellermann, who contributed to the original controversial study, told Salon in 2012.

President Barack Obama ordered the CDC to resume studying gun violence in the wake of the 2012 massacre at Sandy Hook Elementary School, but the agency still lacks funding to do the research.
