Honestly the whole concept is ignorant in the first place. If someone wants to use a silencer to commit a crime they can build a one time throw away silencer in just a few minutes from household garbage and common plumbing parts. So none of this control actually prevents anything.
It prevents the law abiding from protecting their hearing.
The NFA defacto ban on silencers has been one of the worst public health debacles of the federal government.
Go to a gun show. Talk to long time gun owners and veterans. The most common word you may hear will be “What?” because of all the hearing loss.
The pistols used in Hawaii 5-0’s “Didn’t We Meet at a Murder?” had some plastic covers or parts of bottles attached to suppress noise and catch the spent round.
They looked interesting but no idea if they would really work.
Great episode.

That applies to 'gun control' laws and policies generally. They all infringe (at least) on the liberties of Citizens because criminals behave badly.
