A local police officer told a fellow officer after the attempted assassination of Donald Trump that he warned the Secret Service days earlier that the building where the 20-year-old gunman opened fire needed to be secured. Videos show frustration among local law enforcement at how Thomas Matthew Crooks managed to slip away from their view, scale a roof and open fire with AR-style rifle shortly after Trump starting speaking. Trump was struck in the ear but avoided serious injury. One spectator was killed and two others were injured.
