I think the effect is not conditioning, but pissing people off to the point where there is real tangible animosity between ordinary folks and the police. The relationship between non-police and police has shifted from collaborative to adversarial.
I wouldn’t think that the police would want to go down that road.I don’t think they realize how vulnerable they are if the population turns against them.
Maybe its both. I’d agree the current Fed Gov encourages the anti-police movement. Which in the end is to make it so the police will follow orders which would not be followed 10 years ago.
