I think this is entirely possible.
You won't believe this thread
Heh. And didja know that if you type "WTC" using Webdings, you'll get a picture of an airplane, two towers and a skull and crossbones? People can find any kind of pattern in anything and bend it to fit whatever theory they want. I reckon psychics are as good at this as any other glory-seeking crackpot. (Preaching to the choir, much?)
But I don't believe that all "geographical profiling" tactics are amiss or foolish. There HAS to be some sort of pattern, even unwitting on the part of the shooter, if it's nothing else but how far the guy can get on a tank of gas and then get back home. There are patterns, and then there are contrived BS patterns. I think maybe the Keep it Simple, Stupid principle is more applicable here than some mystical (or should that be "mystikal") mumbo jumbo. Still, though, I've bookmarked the psychic thread just for laughs. Lord knows after days of obsessing on the sniper thing, some levity is called for to offset the fear and horror.
