So let me get this straight.
You want body armor to become an NFA item, even though there is no possible way that body armor can hurt someone.
Suppressors can't hurt anyone, either. They have to be paired with a weapon to do that.
It tips the balance away from lawful CCW holders who only have a pistol at their disposal to neutralize a threat.
I'd like it to remain legal to own, because I wouldn't want to deprive someone if that's what they want. On the other hand, when paired with a weapon and taken into a public space, where no one else is likely to have it, that's an issue for me. I'm trying to balance the two without advocating an outright ban.
How many CCW owners that have armor will be wearing it in July in public, unless they're LEO?
