You want sympathy from a cop? You want to get the good cops to push out the bad ones? Show them that you understand what they go through. Show them that you're not exceptional in that respect. Show them that they have nothing to fear from you and yours. Show them that you'll back them up if they do the right thing.
It's like hackers. They're all spoiled white neckbeards living in their parents' basements slobbily eating pizza, right? Just like all the cops are donut-munching bullies cruising around in their cars banging on doors because it's funny, right?
Your comment might make sense, and the attitude you suggest might be appropriate, if police ever took the initiative to take care of the abuses within their own departments. Unfortunately time and time again its been shown not to happen. When it takes people like Frank Cerpico to get anything done (at great risk to themselves) the sort of attitude you propose doesn't really cut the mustard.
For another thing, the stakes are a bit lower if your problem is brogrammers and neckbeards.
