How can people honestly suggest that concealed weapons would've helped Virginia Tech?

Just imagine all the Bushies having concealed weapons! Simply disagreeing with them is treasonous, you know, so we'd all probably be shot as traitors. Ditto for all the pro-lifers, the religious right, and other zealots, fanatics, and bigots, many of whom are paranoid as well as deluded. The rest of us would have to hide under our beds.
