not so often me thinks and if they do have minortiy or non-white criminals its all because of a reason...they are poor, mistreated, misunderstood....there is always an explanation....
the amt. of crimes apportioned to white men is very dissproportional.....
the sad thing is all these show are just so predictable....you know right from the start that it will be an evil, republican, rich, gun-toting white guy....sure spoils the suspense.....lol
I've seen at least one L&O where they took the script from a real life, high-profile crime committed by minorities and turned the perps to Whitey. Haven't seen them do the reverse.
