I don't defend any of Brown's actions for obvious reasons, and don't blame Wilson since he acted the best standard that can be expected of him. As a specific criticism of the situation however i have to offer that your country's judicial system has massively failed in setting up better expectations of police officers by failing to create a less dangerous social climate, by failing to provide adequate training in diffusing situations and by being entirely too lenient and accepting of casual homicide.
I thought everyone knew that by now.

Smugness isn't an argument.
So you might be interested in this from the AP (and not Boing Boing): http://bigstory.ap.org/article/078c82ad45ff4ec6aa1c7744dfa7d...
And also this from the Washington Post: http://www.washingtonpost.com/news/volokh-conspiracy/wp/2014...
fwiw, CNN had a one hour back pedaling with two criminal defense attorneys, today, stating the same things.
It's one thing to collect a bunch of people who tell you things. It's another for those accounts to be accurate, consistent among each other, and match the physical evidence.
