This doesn't meaningfully diminish the problem here: the police in the US are heavily armed, and are trained to manufacture pretext for violence (cf. any number of videos where police shout "stop resisting" or "hands up" repeatedly to people who are already complying).

Ordinary people, even ones who might hurt you, are aware that doing so comes with the threat of the law. The police are the law, and as such are emboldened towards violence when antagonized in ways that the ordinary public is not.
