“The key is to always talk to a police officer with respect and politeness”
That is good advice—even for hard core criminals.
It maximizes the chances for a good outcome—nothing to lose by being pleasant and respectful.
Many criminals raise the suspicions of cops with a hostile attitude and their (often hilarious) loud (usually false) interpretation of the law.
There was one criminal (drug dealer) on Cops who had been doing business for years and had never been caught though he had been pulled over many times.
He admitted his “secret” was that he was so polite and pleasant during those stops that the cops were persuaded he had nothing to hide and didn’t bother searching him or his vehicle.
When I was taking my wife back from her 5 year colonoscopy exam, we went througe the local air base in order to process an veterans id renewal. The APs stopped us outside the front gate and asked, “do you mind if we search your car”? My answer was precisely, “I really prefer that you don’t do that”. That way I really did not appear uncooperative. I explained my situation, but I don’t think it mattered. The APs just said “OK”, and we left. Of course I never carry my weapon onto a military base. Cannot be legally done unless I am carrying it to the armory for storage.
