I'm a little bit late to the game, but I just watched the clip, what a coldblooded murder!!
Frankly, I'm a little bit shocked of the calmly protesting voices of the bystander's, my immediate instinct was to jump into the screen and push this animal's limb off this hapless man's neck. Which ironically, as a matter of fact, if I was successful with that, and George's life would have been spared, then this would be a non-news, and I would be sentenced to many years in prison for assaulting an officer.
