I think that's true, but I also think there's unique, or at least highly specific, aspects to police culture which also come in here. It's come out that a lot of police training is very explicitly "us vs. them" in its approach -- reinforcing the message that every call you go out on could be your last, every person you interact with could be a dangerous criminal, you should be prepared to do whatever it takes to get the bad guys and other officers are your only line of defense. So it's not as much "if I take this guy's misconduct to HR, they won't do anything anyway" as "if I take this guy's misconduct to HR, I will have betrayed my fellow officer." And it's that, that "thin blue line" mentality, that really needs to be tackled.
