This is tragic. I've only seen what was on tv, but it didn't appear the officer was necessarily trying to harm the guy, but rather control him. One thing that always happens in these cases is a rush to judgement and knee jerk reactions. We'll have to wait and see what the reasons were before we hang people. And people want them arrested. That's fine let the investigation play out first. The easiest way to beat a case is attack a sloppy investigation.
