Constitution hating liberal idiots. There's no end to what they can come up with. Semi-automatic firearms must be banned because they can shoot down airplanes. They are a threat to national security. Oh yes they can. Jesse Jackson said so about a month ago. Well now he's enlightened us to the fact they can also blow up trains. I guess we just wouldn't know all sorts of things if it weren't for dumber than dirt liberal morons sharing valuable information.
