Say WHAT? I would think that NFA items represent less than 1% of all firearms in the US. I can't believe that the number of $20,000-$50,000 legally registered machine guns in a state - only 2 or 3 of which have ever been used in crimes since 1934 - means much. (Or it might. I didn't click further, but I had read somewhere that New Hampshire has the highest number of legal machine guns per household of any state -- and also one of the lowest homicide rates of any state.)
More like half of a percent.
This is a hilarious example of how clueless CBS is.
What maroons!
