The John Karr situation is a bit weird. There must be some reason that we don't know about that indicts him. Regardless of how that comes out it seems to me that more weirdo's may be encouraged to confess to crimes. Some people will do anything to get attention from the press; they don't seem to care why they are getting the attention, just as long as they get it. Karr seems to be really disturbed, whether he is guilty or not.
