I can read that "submission and deference" at the casino as conflict avoidance, the arresting officer says to his peers at the station that he "kind of believes" the suspect. He also states at some point that he can't cite (and I infer then release) the suspect because he is not certain who he is, and therefore has to arrest him as a "John Doe" so that his identity can be established. The fact (?) that the suspect now has a police record for this possible farce won't be settled until after the facts are determined in a court of law.

This video demonstrates that when it comes down to it the blunt end of law enforcement is oftentimes a shit show of "seems to work for me" and that goes for facial recognition, shot spotter, contraband dogs, drug & DNA tests, you name it.
