The 2nd Amend was based on weapons and not the right to have pliers.
You can have my pliers when you pry them from my cold, dead hands.
Or you can just borrow them for awhile. I've got a bunch.
I do cringe at the arguments that speak to social utility or crime control. Yes, criminals will think twice about attacking someone if they think a potential victim is armed. No, accidental injuries do not seem to spike up when gun laws are loosened. Those things are true, but we don't need to rely on those arguments.
We have an amendment to the Constitution that acknowledges and protects the RKBA as a natural right. That's where our arguments should be.
