In pictures: Trump injured in shooting at Pennsylvania rally
CNN
Greg Smith, interviewed by the BBC, said he told police officers about a man with a rifle on the rooftop three to four minutes before the shooting took place. Smith said: "I'm thinking to myself 'Why is Trump still speaking, why have they not pulled him off the stage'... the next thing you know, five shots ring out." [1][2][2][3][4][5][6]
