Then what do you care what other people do if it's not hurting you or something you care about?
Honestly, I'm a bit of a Devil's advocate, but really, ever since the walmart debacle were some schmuck got shot by police while carrying a toy rifle, I'm just trying to open your eyes to the possibility that it's not the best option, as far as constitutional activism goes. There's nothing stopping some yahoo from the anti-gun crowd from calling the police saying you're threatening them with a rifle, and things go south, quickly.
As for the civil litigation thing, as I said before, we live in an extremely litigious nation. People can and do file lawsuits for anything and everything. I mean, if some lady can get 2 mil for burning her snatch with hot coffee, you honestly believe some moron couldn't think something up against an O/C'er?
Food for thought, that's all.
