I have. But in this case, reportedly nobody who worked with him saw anything amiss or saw any conflicts or problems. He had just resigned from the job "for personal reasons," but there was no indication of hard feelings.
I just do not understand why, when people snap nowdays they decide to kill. In the "olden days" you just went out and got really drunk and maybe got in a barfight or something.
I can even sort of understand (but not condone, of course) somebody getting so angry at a particular person that they wanted to kill that person -- but everybody in sight? I just don't get it.
Is it the increasing isolation and loss of feelings of community that some of us feel, or the lack of traditional support systems like extended family to talk someone off the ledge, or loss of socioeconomic safety nets? Or sitting on the internet reading stuff that inflames hatred or anger or feelings of desperation?
