 So again, how close was Crooks able to get here? Well, he was up on that rooftop of that AGR building, which is a local business. That's about 200 yards or two football fields away from the stage where the former president was speaking. Then a US Secret Service counter sniper took him out up on that rooftop, people screaming and shouting, trying to run for cover. Investigators haven't said yet what the motive was here for this shooter.
