Trump rally gunman stopped firing after local officer shot at him
Thomas Matthew Crooks paused shooting at former president Donald Trump after a local law enforcement officer assigned to a SWAT team returned fire, and Crooks did not shoot again before he was killed by a Secret Service countersniper,
It has been reported that a local officer fired at Crooks, but the analysis suggests that the officer may have played a more important role than previously known in responding to the attack
..shortly after that shot, Crooks altered his positioning, the official said. Crooks stopped shooting at the rally site and slumped down behind the crest of the sloped roof where he was perched
This has been known for a little bit.
