I thought he was in fairly good control considering the two clowns that tried bum rush the cop before he waved his pistol against him. I see your under the linguistic programming spell of the talking heads! I think it’s perfectly normal considering the conditions. What was abnormal was that no dog got shot!
He was hysterical, the loss of control over his language should have gotten the other cops to go calm him down before he started attacking and even pulled his gun.
The guy is a Barnyey Fife, if you remember, even in Mayberry, once the kids realized that Barney was so easily rattled that they picked on him.
This hysterical guy was not the cops we used to know years ago, even in the 50s and 60s, kids would have singled him out for teasing and harassment.
