I remember getting “the talk” from my father about how to behave when stopped by the police... say yes sir, no sir, don’t move unless officer tells you to, then do exactly as the cop says. Above all, don’t try to outrun them (you won’t & they might shoot you) & don’t resist (you will get a beating or worse). He told me most police were good but that some became cops because they wanted power and those cops could be very dangerous. This was probably about 1964 or so.
