Charles Krauthammer used to be chief resident for psychiatry at Boston General if memory serves; he says we need lunatic control a lot more than gun control. He says at least some of thepeople doing this stuff would have been locked away prior to the 1970s.
I always shudder to think of the patients who came to the cold, clinical Krauthammer for help and advice. Sort of like the doctors who treated Marilyn Monroe at Paine Whitney...creepy.
