You know, I've seen some fucked up shit on Cops before, but at least it's usually from the perps.
I don't think I've ever seen anything more fucked up then the time they tried to arrest a woman simply for...well, basically for not wanting to die. The police went to a grocery store parking lot and held a fake drug deal and when a random bystander didn't immediately jump in and try to stop it they jumped her and told her they were going to impound her car. When she told them she needed the car to take her kids to and from school they threatened to take her kids away and told her she was lucky she wasn't being arrested. For what? Being intelligent enough to know that an unarmed 30-year-old woman isn't a match for 4 heavily armed drug dealers?
Of course, I've lived in the United States long enough to know a good portion of our laws are only meant to keep people from having fun, so it's not that surprising to see the cops do stupid shit when pot or hookers are involved. Shit like pulling over a man and arresting him simply for being in a part of town known for hookers and drug deals. I'm not saying he wasn't after a prostitute, but when you haven't seen the guy do anything you can't arrest him for what he might do. You're not Dick Tracy. It doesn't work for you.
Of course police are also not paramedics so watching them stand around and question a guy who's just been shot in the back four times isn't that surprising, given the ambulance wasn't there yet.
It's all kind of expected. We know the police fuck up sometimes. But guys, when you show ALL THREE of these in one episode, it's going to take a lot more than saving a family of cute* racoons stuck in someone's chimney to save your reputation.
*Also, guys? Racoons are not cute. They're filthy vermin. They are highly aggressive and will attack people and pets, often spreading deadly diseases such as rabies. They break into homes and businesses, causing property damage in their search for food. In the end, you just released a bunch of horrible little monsters back into the world to cause further pain. Way to go.
