Congress did not prohibit firearm research at the CDC. I know. I was one of three medical doctors who testified before the House Appropriations Committee in March 1996. We showed the committee hard evidence of the CDC leadership’s overt gun control advocacy. It was that anti-civil rights advocacy that Congress quite reasonably prohibited, not firearm research.
The events of that era are documented in my three-part historical series, “The History of Public Health Gun Control,” at Doctors for Responsible Gun Ownership’s website, drgo.us.
