These stories actually make me wonder.
I've never had a bad encounter with a cop. Knock on wood.
Obviously, there are bad apples in any group but I have to believe that the occasional "bad cop" is an exception, not a rule.
Not to disparage the OP or any other person with a situation like this, but the wisdom of the ages remains, "Until you have both sides of the story, you're not in a position to make any judgments." Even then it can be difficult to get to the bottom of the story. For the sake of discussion, we can take it at face value here.
Still, with as many encounters as cops have with the public, if the majority of them were bad encounters, we'd hear a lot more about it than we do.
