Well it's been reported they attacked at least 3 officers, they had to go to the hospital, one with a broken nose and that's whose blood you can see on the floor during the video. Not just the MSM, but didn't the police confirm this?
So they are violent criminals
Seeing the video again, the person in blue was NOT restrained at that moment, his hands were free, that officer wasn't taking any chances he was about to jump up and snatch his gun, however remote that chance was.
And now we have a problem, a large chunk of Muslims, (mostly new arrivals at a guess) as they feel as if they are above the law, and feel they have the God given right to do what they want. We have a problem, a problem we need to quashed quickly otherwise we're going to have a war on our streets. Them vs the police and if this continues, complete civil unrest involving everyone. The police are failing in their duty.
