"A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed."
It's pretty clear to me.
the NRA wouldn't dare take that into federal court, and you and I both know why.
Yes, because they'd lose. But that doesn't make these laws constitutional anymore than Roe legitimately found a right to privacy in it.
I can't claim to be a constitutional expert on the 2A - but it seems to be alot of balancing going on there. "well regulated", what does that mean? OK, to keep arms is clear - but where can I "bear" them? anywhere I want, without restriction, including concealed carry? I don't know.
I'm not in favor of federal gun laws, I think a state based system works best.
