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.

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.

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

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.

I like to have success experiences rather than failure experiences. So I'm more likely to compete in things I'm good at, and more likely to spend time on the things I expect to succeed at.

Killers seldom meet the legal standard for insanity, which is quite different from the way most people use the word every day. Killers may be disturbed, but that doesn't necessarily mean that they can't tell right from wrong or are compelled to maim or murder.
