Snoopy: Well, shoving the guy was unnecessary no matter the outcome. So that's one point. Police here are trained to show more restraint. Certainly the officer didn't mean to bring upon the man's death. But shoving the man served no useful purpose. With that I agree.

I also see Czuch's point. I know that whenever I've been pulled over, the man in the uniform represents the authority of the state. He is called, "sir' by me. Or "officer." I show respect and talk decent to the man/woman. I know they have a hard job to do. If I am near the G20 summit, I choose a route that doesn't complicate the job of the police. They have been dealing with rioters etc. So being smart, I know to keep away from the front lines. This man apparently didn't get that message. He bears some responsibility here. It doesn't excuse away the officer's over-reaction (IMO it was an over reaction), but it does put some blame upon the man that died.
