Not in my case. The people who told me the stories were well-established adults who very rarely lose their cool (but some cops have a way to piss you off so they can then justify their violence towards you).
So a good general suggestion from your side but doesn't apply to what I've heard and experienced.
I’m skeptical that you’ve sampled a good cross-section of experiences. It sounds like you exposed yourself to a high volume of anecdotes from a narrow category of respondents. You may also have been exposed to liars or exaggerations; you yourself aren’t lying.
We all judge by what we see. Obviously that's never the whole truth -- that much has always been true. So I never claimed to have the whole truth of the situation; of course I don't, it would be hugely naive for me to claim otherwise.
My general stance basically is "don't look at what's written, look at what people can do and get away with it because that's exactly what most people will do".
