Security video shows K-9 alerts to Cole Allen right before he tried to rush through security, but handler pulls the dog back. 31-year-old Cole Allen is seen walking around The Washington Hilton in DC in the day before the attempted ass*ssination of President Donald Trump. He’s then seen in the top left of the security footage, walking into a doorway, as a K-9 alerts, and appears to want to check him out. The handler pulls back on the dog, and moments later Allen races out of the doorway and opens fire at security.
