I agree that there is a silent element, (maybe even a majority), but that is because you don't report what is functioning correctly. I do think that there is a system-wide problem, however, when you see groups of police officers doing the kinds of things we have seen in videos recently - shooting unarmed, prone suspects, beating people and then fabricating self-defense stories, using violence against unarmed and non-violent protestors. If law enforcement were not pervaded by a culture that supports or at the very least protects those who engage in that behavior, we would not see so much of it.

I don't imagine that the good officers can really step forward and complain if the culture is protecting it. My friend from high school eventually left the force because being gay, he was treated horrifically including not being provided backup when he called for it. He felt that is life was in danger and he said he dd not have any recourse other than to take the matter outside to the judicial system. He saw that as a losing proposition given the fact that his supervisors were aware of how he was being treated, and instead, he changed careers.
