 A gunman on a roof of a building some 170 yards away from Trump fires multiple rounds. One attendee, 50-year-old former fire chief Cory Campatori, was killed. Two others were seriously injured. And Donald Trump himself took a bullet through his right ear. He crouched. The Secret Service gave him cover. Then, instinctively, he stood, raised his right fist, and shouted, fight, fight, fight. Wait, wait, wait.
