And since the 2nd doesn't mention them ( same as cans ) they are a candidate for regulation?? A car can be used as a weapon; yet mufflers aren't regulated! Graham, I am clear on the NFA regs; but do they make any sense to you on cans? I realize your opinion is just that; but curious to as your thoughts?
I'm thinking that the apprehension people have about suppressors is partly utilitarian and partly cultural.
In a practical sense, legislators in game states are wary of tools that could make poaching easier. Crazy, I know, but to the uninitiated that's a big fear. Education dispels the myth, as happened recently in Wyoming.
Culturally, the American public has always looked down on tools, like suppressors, which were designed or intended as an aid to clandestine activity. It's simply a prejudice, probably fueled by the portrayal of 'silencers' in movies as used only by bad guys for assassinations.
But our bias against all things quiet and secretive also exists in a wider context: We see it in punitive laws against possessing brass knuckles, saps, and knives that are designed not to look like knives.
Historically we have always had a bias in favor of being up-front and direct, which resulted in a stiff resistance to concealed carry (most state legislatures having favored open carry laws until not so long ago). We also see it in our military doctrine, as US doctrine has always favored an 'in your face' style of both movement and command.
I agree, it makes little sense in our modern society to regulate suppressors as NFA items, but so much of gun control is rooted in emotion, prejudice and racism rather than in common sense.
