 The official narrative is that two days ago in broad daylight, a 20-year-old acting completely on his own, armed with an AR-15, managed to climb onto a rooftop carrying a rifle just 400 feet away from where Donald Trump was speaking at a rally in Butler, Pennsylvania. This was one of only a handful of rooftops in the area. It was the one that offered easily the best view of the stage where Trump was speaking. The gunman was able to shoot Trump and three of his supporters, killing one of them and seriously injuring two others before the Secret Service managed to take him out.
