You make good points in your post #26. Why did this guy behave so dangerously around the Ranger? He apparently was looking for trouble. The Ranger had reason to fear the man, because why else would he tell him to turn around. The guy’s behavior is just bizarre.
My local PD “5150’s” people all the time...(psych hold). They also have a device called a “wrap” (sort of a straight jacket) and tasers, no police shootings in decades (except a fleeing armed bank robber about 20 years ago who survived after taking a shot at the cops from a getaway vehicle). It is all about the training and evals..
