Other than in Hollywood movies, is there any crime that is enabled with a suppressor that isn't enabled with just the gun itself? Is everyone collectively harmed by one person possessing one?
Lots of gun owners think the rules around suppressors are silly, because the reduction in noise is a huge quality of life improvement for everyone around you -- and a glance at the police blotter in any major city should show that gun crime isn't exactly hindered by the lack of suppressors!
and... most importantly... a suppressed firearm is still not quiet! - and is not hearing-safe to fire indoors!
Hollywood and video games have convinced the population a suppressor is impossible to hear and you can shoot people in public without anyone knowing. Ridiculous, to say the least.
Even then, it's still obvious a gun was fired. The John Wick scene in the subway is so laughably absurd, but so many people think that's what happens when you screw on a can.
