Amen on law-enforcement
My brother a former county deputy has that same "might/authority makes right" switch.
He often tries to turn a discussion on its head by personal attack (e.g. questioning what is wrong with me when I question authority, nuance of law, or behavior of law enforcement.)
In-so far as to whether a police officer is right or wrong he would argue it is irrelevant. Civilians are required by law to obey law enforcement requests.
Of course I'm painted as discontent when I mutter "REASONABLE requests, brother."
