“I’m as pro-2A as they come, and I really do think he should not have a gun. Maybe mandatory gun training? I don’t know.”
Mandatory training is a tool to eliminate gun ownership or at least severely curtail it.
Besides you can’t train out stupid.
I know what I’ve posted is conflicted, but the fool shouldn’t have one, waving it around loaded, in a drunken tantrum.
I know of a few instructors who probably could, but they don't use NRA-approved methods of instruction. Basically, you do something stupid, they hurt you, and you don't mess up any more.
