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.

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.

Counter to the public's thinking, the celebrities who attract the largest number of stalkers - and typically it's not "if" a celebrity has a stalker, it's "how many" - are neither the most glamorous nor obnoxious, but rather the ones who seem the sweetest and most wholesome. They appear approachable.

Only the individual can decide what level of risk she can tolerate and what level of freedom she's willing to sacrifice for the sake of safety.

One of the problems with studies that examine the effects of violent imagery is that they typically use mentally healthy psychology students. If you want to do a meaningful study, show movies like Body Double and Copycat to a group of sexual psychopaths the day before you release them.
