Rampaging Killers

Dr. Helen offers some insight into the minds of a lot of these rampage killers, and suggests ways that these people can be detected and helped before they kill.  PDB, who is a native of North Carolina, offers some other commentary on the situation.  I would add that I think the media has a lot to do with these rampage shooters as well, as Uncle points out, they always seem to come in threes.
