We've had 20 years of mass murders throughout which I have repeatedly told CNN and our other media, if you don't want to propagate more mass murders, don't start the story with sirens blaring. Don't have photographs of the killer. Don't make this 24/7 coverage. Do everything you can not to make the body count the lead story, not to make the killer some kind of anti-hero. Do localize the story to the affected community and make it as boring as possible in every other market. Because every time we have intense saturation coverage of a mass murder, we expect to see one or two more within a week.

One of the few times I'm hit emotionally is when I listen to the tapes sadists make of torturing their victims. There the person is currently suffering, you can hear them suffer, and that calls out for an empathic response. But when they're dead, when they're no longer suffering, when it's over, it's hard to feel empathetic for the corpse.

With rare exceptions, people are responsible for what they do.

Our job should be like any other forensic scientist's - we should be truth seekers who are not partisan, who do not have any interest in the outcome, who call it as we see it no matter the consequences. But it seems a lot easier for chemists and anthropologists and pathologists to take that neutral role than it does for psychiatrists.

One of the biggest mistakes celebrities make is being overly friendly. They allow photo shoots in their homes, even their bedrooms and bathrooms; they send fans autographed pictures. All that serves to support viewers with a delusional relationship with the celebrity.

Consider surgeons and their work. It's unthinkable to put your hands in the warm blood of another human's gut. Even with rubber gloves on. Who'd want to do that? But surgeons get over it.
