Has anyone else thought that this nutjob was trying to commit suicide by police? I've been to the Holocaust Museum several times, and the first thing I said when I heard about the shooting was, "He couldn't get too far - it's probably the most secure museum in DC." His choice of entrances says a lot, too.
I'm very interested in hearing whether or not he has a terminal condition, because that would give him a chance to "go out with glory".
