I think this, from yesterday, covers what I think about gun laws:
"If you want every weapon currently in one's hands registered, fine, I'm good with that. If you want to impose ridiculously long prison sentences for having an unregistered firearm, cool, I'm good with that also. If you want government round-ups of specific firearms that are newly illegal, nope, not having it."
I have no problem with any of this. Selling guns without proper transfer paperwork would be illegal. Problem solved. Of course, our powerless ATF and government probably couldn't stop it from happening but it would be illegal.
