My initial response to this thread is, "Good!".
After watching the video and reading some of the nonsense in this thread, it's still, "Good!". 99% of the time, I will side with police, especially when all of the evidence isn't known. All I've seen is some video that has gone viral. For all I know, the police gave this guy 10 chances to move or disburse, and he continued to disobey orders. For all I know, they were on private property. For all I know, that guy could've pulled a gun. For all I know...
See, that's just it, I don't know -- and neither do you. Stop making stupid blanket statements because of some propaganda laced video/commentary/news article. Ockham's razor is usually a safe bet, especially where the police -- you know, the guys that put their lives on the line every day to protect yours and my freedoms/rights -- are concerned.
