Their costume makes them easier to identify: in public, down the sights, and in the courtroom. It won't matter even if someone does tell them. They don't understand any language but violence.
As a brown man, that's why I've bought a rifle and handgun. If they wish to have a "conversation" with me, then we'll "talk".
Thinking about MAC10 bump fire between my 9 and 5.56. But, fuck it's expensive.
Bump fire isn't a device. It's a technique that's easier to perform with certain firearms such as a suppressed MAC10. It can't be made illegal.
If this is your way of saying you'd like to arm yourself but cannot due to local law or your status, then explore a replica Remington Model 1858. If that's not legal, a muzzle loader. And, if that's not legal, bear mace.
Take a safety class. If you don't want to learn from a LEO or NRA asshole then engage the SRA.
I misunderstood and thought you were talking about a bump stock, which is a device. I own firearms, but all center-fire, semi-auto rifles were banned in my State this year.
