Cops were either just outside or on the way. He didn’t want to be arrested. I heard him tell the story.
Promptly leaving the scene was a prudent thing to do, but I doubt he “ran out”.
Guarantee you no one in that Coronado, CA bar frequented by SEALS, had any idea of who the assailant was, or was even able to give the police a physical description. That would include the bartender. Given the calm demeanor of the SEALS that were present when police arrived, I doubt the police even asked.
Ventura’s reputation is well known by most in those parts, especially after he tried to pass himself off as a SEAL.
