I still haven’t seen or read anything about how the murderer got the silencer.
To your question: every American who can legally buy a gun should be able to buy any accessories for guns, and be able to carry them anywhere and anytime.
Also, any governmental entities infringing on the right should get mandatory fines and prison time.
But, I’m weird.
Chances are that he paid his $200 and endured the 8-12 month background check in order to get his tax stamp for it.
If he had obtained it illegally or had fabricated it, that would have been shouted from the rooftops by the MSM. But if he successfully underwent a background check, that undermines their argument for 'universal background checks,' so all you'll hear from the MSM are crickets.
