You saw a rioter, prepared with a gas mask so he could #resist. He was ordered back and resisted. Am attempt was made to disperse the crowd with non lethal tear gas. He resisted. The he got nailed in the batteries with a pepper ball (misidentified as a rubber bullet). He didn't resist.  He thought that he was prepared for war, but forgot his cup.
 
The Phoenix police did what the Charlottesville police could not do,  they prevented antifa from violently engaging a group of people.

Nice shot, man.
