I just want to point out that when I was visiting Oliver, British Columbia, the local news was all about a police officer in nearby Kelowna, who had booted a man in the head, which was speculated to cause brain damage. The surrounding circumstances do not, in fact, make it sound justified.
The situation was apparently that the suspect was seen 'discharging' a shotgun at a local golf course, to scare away geese. There's no word on whether he had been intentionally aiming at geese, or was firing blanks or live rounds, but he has apparently been hired to do this in the past. Now, reasonably, some people may not know this, so an RCMP officer responded to the situation, and went to arrest the man at gun point. So far, this isn't totally out of line. No, when it crosses the line is when the man is on his knees, in front of the officer, who is repeatedly shouting at him to 'get down on the ground'. I'm assuming the officer wanted the man's hands down as well, as that's what the man did. The officer, though, was already in motion, and had kicked the man in the face.

So... I can understand why some people might be hesitant to joining the force. One officer is not indicative of the entire force, and if it makes any difference, this was the Royal Canadian Mounted Police, but... it can make one worry about where and how police brutality comes about, so just saying 'he should join the cops' doesn't hold as much sway as, well, as it should. And it's a shame.
EDIT: I know the video says "raw", but there are related videos on Youtube by the same poster, CastanetNews. Many of these add extra insight into the situation if you're interested... okay, screw it, here's a video link: http://www.youtube.com/watch?v=JbdareHU4Ik&feature=relmfu
