Its scary when you think about.
This dude I work with just got his first gun and license to carry in December. He was telling me how he was with his kids at the park the past weekend and he saw some "homeless people" walking from the woods, he said he placed his hand on his gun just in case. The people were just waling from the woods, that's it. Not bothering him, not talking to him, nothing.
I told him he was the kinda person I'd be most worried about, not the people coming from the trees. He's >one of those conservatives< of course. Dude just got his gun and is already thinking like this.. thousands of people are out there just waiting for the moment to use their gun on someone.
