What did you expect? When police departments investigate themselves, do you really think they’re going to find themselves guilty. That’s like asking whether a criminal if they’re guilty. Of course they’re going to say no. This has to be one of the most idiotic things practice, asking police departments to investigate themselves. To anyone that thinks this practice makes sense you’re not very smart. Asking police departments to investigate themselves fot wrong doing is like controlled opposition, nothing productive is going come out of it. It’s only a waste of time and resources, that would otherwise be useful.
