85% of what people do is habit. So when they have a large set like this "habit" starts excluding people very quickly as they are just driving to common places. So if you are tracking somebody you dont know fleeing, they stick out in the numbers quickly... If you are tracking somebody you do know you can guess where they might be. Kidnappers and bank robbers aren't that smart when looking for hiding places, and you probably already have them tracked going there.
To a certain extent, all it really does is SUGGEST you belong or don't belong in any given location. There might be a murder in an alley, but data shows you go to a comic book store blocks away every week so you probably aren't involved. Generally the data is going to clear more people than it makes guilty.
Of course I'm a huge fan of Numb3rs and Criminal Minds that show this kind of stuff being used properly by honest people... Emphasis on HONEST people.
