Who's Mad?

A while back, Mike Jackson had a platinum album called Bad, in which he asked in the title song, "Who's Bad?" In the run up to deal with all things evil about the Virginia Tech massacre, there's just a simple question to be answered. As the talking heads and security chiefs and safety consultants fill the airwaves with what-ifs and why's, there just one simple question. As the world ponders the senselessness of a depraved mind that exploded into uncontrolled rage and hostility, there's just one question. As psychologists, psychiatrists, and other purveyors of the science of mental health, look to peel back the layers of a final psychotic episode in the life of another wanton killer, there's just one question. How will the rational ever explain the irrational? Who's mad?
