Not all cops are bad. Hell, MOST cops probably aren't what we'd call "bad." But as long as they are not soundly censured and driven out of the profession by those who are, by our perspective, "good," (which means those who don't engage in bullying behavior, expect special treatment because of their job, and/or aren't actively corrupt) we shouldn't anticipate the "Cop-Hating" to diminish by any perceptible percentage.
Cops should be held up to a higher standard, given that they are trusted to carry weapons and regulate the behavior of the rest of us. In consideration of this fairly obvious fact, they should welcome rather than oppose such things as citizen oversight and the public filming of their interactions with members of the citizenry. It would protect THEM from wrongful charges of abuse of power, brutality, or corruption as well as protect citizens from said behavior.
And all the calls for an end to it will fall on deaf ears as long as their defenders fail to realize one thing. Most of us are not "Cop Haters," but "BAD Cop Haters," and we really wish more decent cops would publicly join our ranks rather than reacting so defensively. I have met as many what I'd consider decent cops as bad ones. So I know they're out there.
If they want to change public attitude, they need to speak up and let us know that they're on OUR side, not the side of their criminal co-workers.
edited for clarity... (I forgot the word "diminish.")
