I watched Steve's video explanation of the case, and it was very interesting. Some police do get uppity, are rude, and abuse their position of power. This was a perfect example, and the cops that do this should be weeded out of the department. If not, they create animosity and eventually may cost the city large amounts of money.
Just like any profession, if you hire enough people some are not going to work out. Get rid of them before things get out of hand.
