That's fair enough and I understand completely where you are coming from there, and also the problems that discretion can cause at times if it's not consistent or if it is prejudiced or perceived to be. I do honestly have the utmost respect for decent police officers and the job they do regardless of where they have to do it.
The recent hurricanes also reminded me of one of the most heart-warming stories I have read on the internet where the New York officer bought a homeless guy some expensive boots and thermal socks during a particularly cold spell, and i'm sure it was just before a storm/hurricane was due to hit. I do feel things like that are often not picked up on or appreciated enough where at times it's far easier to attack the bad cops all the time. However, that's not to say that a lot of the stories of brutality and shootings don't deserve the attention they get, and often maybe even more, but still....... Feck, I've gone off on a tangent now too. Apologies.

Since we're on tangents already....
I believe any instance of "cops behaving badly" should be highlighted, addressed, and figured out how to avoid it happening again. I just usually take issue with how people sometimes tend to address all cops. We're human too, we make mistakes. Yes there are bad cops, just like there's bad accountants, fishermen, barristas, etc. obviously cops have a finer line for margin due to what they do, and dealing with people's right and civil liberties, and they should be held to a high standard, and the ones not fit for the job should be removed.
That being said, people seem to sometimes overlook that we get plenty of abuse just for being cops. I won't relate it to it being the same discrimination someone gets for the colour of their skin, but just because I chose to sign up to be an officer, that the abuse is should just be accepted to be a part of the territory. I signed up to try and make a difference and because I want to help. Does that mean I should just accept that people tell me they hope my kids are raped by black people? Just because I put on a uniform, a badge and a gun, doesn't mean I'm immune to making mistakes, and taking things home on my shoulders that I don't tell my family about, because I don't want them to have to try and imagine the things we see and deal with.
Just this weekend we had felony stops on the freeway with traffic flying by, tasers deployed in a hospital after someone high on meth tried to grab an officers gun, a guy with a hole through his leg from his motorcycle crash. Then I still have to be polite and professional to the next person I pull over for going 94 in a 65 that no he can't get a break, and then listen to how it's my fault and I ruined his day/weekend/life.
In my opinion, and yes I'm obviously biased

is that there's so many cops you never hear anything about, that could tell you just as many, if not more, stories about what they have seen and dealt with, and never set a foot wrong. They shouldn't be taken for granted, or even worse, lumped into a "all cops are (insert choice of word here)".
/end long tangent that I said I wouldn't go into
