I can't help but wonder if Trump wasn't hoping to set up some kind of confrontation between his rally goers, and the protestors, in order to get video for his campaign. Trump kept stoking violence throughout the rally, saying if his people took on the BLM protestors, it would be no contest. He's got all of the tough guys.
On of the rally goers said he got a face full of pepper spray from the police as he left the building. He was older, ex-military and looked it - fit, educated, and well spoken. He wasn't injured by the spray, but he had no kind words for the police, saying they should not have been there in those numbers. They don't do things that way in Oklamhoma.
