What was Jeffrey Dahmer's cause? Or any number of other serial killers? Forget serial killers, how about the guys who shot up Roxborough high school and also killed someone the day before? Are they all mentally ill? Psychologists say no. Not every heinously violent person gets that diagnosis.

The SEPTA police captain here doesn't have any qualifications to make that judgment, and saying so downplays the severity of the attacks.

People here need to do a little reading.
