It's not a "gun problem" at all. It's a murderous nutjob problem. Banning bump-stocks, or even real automatic weapons, is misguided and foolish (at best). At worst it is a deliberate effort to disarm the people prior to oppressing them. We need to concentrate murderous nutjobs, not get distracted by the foolishness of banning objects.
You said it and I agree completly
Agree.
IMO, anything the cops/feds have in their arsenal should be legal for the citizens. The point of 2A is that the citizens should have the means of protecting themselves against an oppressive government. So if the cops/feds have grenades, they should be legal for the rest of us.
