The issue in law enforcement is to try to predict and prevent, which is my point. If one can predict who is 'predisposed' to act on criminal urges, crime would be reduced substantially. \r\n\r\nI am over-simplifying, but I am sure you get what I am saying.\r\n\r\nSounds like Minority Report. :D No, I understand what you mean. Are you involved with this professionally or is it just an interest?
