whathehadas, If it happens once a week like it seems to be (and that doesn't include the incidents that aren't covered by the media) then it should be thought of as all the time. And I'm including all races and not just shootings but body slamming, which seems to be a favorite of police, and other forms of beatings. I have seen at least a dozen videos in the past few months.
As for your not being pulled over let me ask you, what type of neighborhood do you live in and how new is your car?
