Lockdown at St. John's? From the mailbag: "A friend of mine who goes to St. John's just sent me a text saying that someone wielding a rifle is being arrested right now on one of the quads at St. John's. Thought you might be interested before the crews and such go out. No one was shot or anything but students are being told to remain in the buildings until it's deemed safe to leave." Update: It was the Catholic university's Queens campus and "The man appeared to be wearing a President Bush mask, according to preliminary information from law enforcement officials." We love "appeared." Or maybe it was President Bush??? [WNBC]
