If there's one thing I've learned about the legal system from my arrest and court experiences, it's that just because the police do something wrong does not mean that you can stop them from doing it. People don't get their miranda read, they don't get to make a phone call to let anyone know where they are, they don't get their medication, they don't get a meal in line with their religious or dietary restrictions, they don't get a clean bathroom, and they certainly don't get treated with any modicum of decency. Well, it's not really anything you can prove and even if you could a judge won't care much because it's hard to assess damages for intangibles like that and the public won't care much because you broke the law and deserve what you get. It's a pretty fucked system.
