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.

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 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.

Celebrity stalkers also are not necessarily fixated on one person as the public thinks. Rather, they tend to switch targets, going from, say, an athlete to an actor to a politician.
