Multiple camera angles caught a Trump supporter sucker-punching a black activist who was being removed from a rally following an attempt to disrupt that rally by protesting. The use of several cameras at different angles to capture his removal -- and the subsequent violence -- makes it difficult to claim the offense was faked or is being misunderstood.
Will Trump try to talk his people into not taking the bait? Does he actually have that much control over the passions he's riding toward the nomination? I am doubtful on both questions.
