Earlier quoted context omitted.
Sometimes this translates even down to the individual level. I've watched a lot of police bodycam videos and it's surprising how many people make their situation worse by being loud obnoxious tightwads when calmly answering questions and handing over your license would have you on your way in 5 minutes.
I get what you're saying, but being an obnoxious tightwad isn't actually against the rules, and it's not OK that there are some societies in the world where being an obnoxious tightwad towards a force ostensibly tasked with PROTECTING their fellow citizens (including the obnoxious one) will take this as a cue to 1) violate your civil liberties/rights, and/or 2) commit bodily harm to your person, and then 3) get away…
What are you doing to justify feeling like this? Is it just out of abundance of caution? When I interact with police it's usually for boring reasons - like I broke some petty law and they justifiably question me about it (and more often than not just let it slide, but they don't have to -after all they're just doing their job).
