Personally, I think suppressor should be the least of illegal things about firearms.
The majority of the people I know with one have it so they don't bother their neighbors as much and they have a little extra buffer zone for their earpro.
I'd much rather it sound like my neighbor is using a large sledgehammer all day than gunshots.
The masks, lack of clear identification (not "I'm a cop" but actual identifying information), and what looks like 270 rounds of ammo waiting to go for a supposed ~~kidnapping~~ deportation are of FAR greater concern.
