But if you could be 100% accurate at predicting crime, then you'd go stop it. Then the algorithm would be shit at predicting crime because there wasn't any anymore? A degenerate case of 'predicting crime' could be, predict zero crime. Because you should have stopped all the crime I was going to predict! </humor>
