It was a long, hot, steamy day in Butler, Pennsylvania when someone crawled onto a rooftop that had baked in the sun, set up a rifle and tried to shoot Donald Trump in the head. We don’t at this juncture know anything about that person for certain except that he is male, and that his presence on that rooftop surprised the countersniper teams designated with protecting the former president, giving him the split seconds needed to fire off a number of shots, killing at least one rally attendee and injuring others.
