In fairness, most of the auditors are only partially informed about the law too. However, if they are actually following the law and the police violate their rights, frankly they should be paid out and hopefully the police will learn the hard way what the law is.
That said, its unlikely since the officers are so isolated from accountability that its rare that there are real repercussions for them.
How hard is it to know that a person has a right to film anything they want in public without getting harassed?
