This is a reasonable belief, but incorrect. Philando Castile did everything he was asked to do, and was still murdered in front of his partner and child. There are many, many, many cases in which compliance gains nothing at all, and quite a few counter-cases in which protesting and waving a camera is likely (impossible to know for sure) the only reason people who are the subjects of police aggression are still alive. Many people are not aware of these things off the top of their heads, but most black people--who are statistically six times more likely per capita to be killed by cops--definitely are aware.
