Who knows what happened here. Conservatives are latching on to this part:
Kenneth Gladney, 38, a conservative activist from St. Louis, said he was attacked by some of those arrested as he handed out yellow flags with “Don’t tread on me” printed on them. He spoke to the Post-Dispatch from the emergency room at St. John’s Mercy Medical Center, where he said he was awaiting treatment for injuries to his knee, back, elbow, shoulder and face. Gladney, who is black, said one of his attackers, also a black man, used a racial slur against him before the attack.
… which is horrible, but generally ignoring the part about police macing liberals for taking pictures. Sounds like an all around cluster fuck. I expect to see more of this.
