First, a chief of police was interviewed on CBS News a while back. He said there are thousands upon thousands of police interactions with citizens every day but all anyone ever hears about is the one bad one that happened one time.
Second, and this might sound off-topic but I hope you get my point. I was helping a guy move, a few months back, along with one of his friends who's a rookie cop. This took place over several days. Each day, we rode in a truck a coule of miles and, along the way, he would occasionally say, "Expired plates. Expired plates." cause we couldn't go a mile without him finding one. And not just by a month or so but, in one case it was almost a year.
Which brought up racial profiling, as you could imagine. He said, "There is no race indicator on a radar gun." And "When I see something go wrong and I light it up, I can't tell who I'm pulling over, much less what race they are, until I get out of the car. And I don't care. You could look at my ticketing and arrests for the few months I've been on the job and say I do racial profiling cause most of them are [insert what you know it is] cause, from what I can tell, most of them do the things that get them tickets or arrested and put in jail."
I think of that every time I see an article, here on HN, and the comments by people trying to blame the cops for everything as if they're against us.
EDIT: As I pointed out, right away, the first two commenters entirely missed my point.
