That's two crimes committed with NFA weapons in the 80 years since the NFA has existed. One committed by an active duty police officer and the other by a former police officer.
And to the previous poster I'll add that production of AR15-pattern rifles and carbines alone for the commercial market averages about 380K units per year since 2008. Adding in non-AR pattern "military style" rifles brings that number to about 480K per year, or about 20% of all rifles produced and sold commercially in the U.S. The AR15 is undoubtedly the most popular rifle in the U.S. and that includes a hell of a lot of folks who can't reasonably be classified as "rednecks."
