Interesting that a lone cop can cuff someone who has run but eight cops cannot with beating the dude up ...
As I said, part of it is a matter of psychology, and reading someone’s behavior and the circumstances.
911 might be called on different people for similar reasons, but the two people the police are dealing with, and the two situations, are going to be different, and have to be treated as such.
What was the prior record of the motorcycle rider? And all-in-all during the chase he might not have shown the same reckless disregard for others as the truck driver did, and perhaps the truck driver also showed a desire to be violent. Perhaps when he tried to ram the police car days before, it wasn’t just to get away, but showed a desire to injure police.
The motorcycle rider had also tried getting away and hiding, and saw he couldn’t. The truck driver’s sudden giving up likely seemed to make no psychological sense.
