If there’s a selection bias causing you to only ever see evidence pointing in one direction, you probably shouldn’t update your priors. Cops doing their job in a routine way doesn’t make the news. Cops taking steps to de-escalate things and avoid killing someone doesn’t make the news. Cops killing someone (justified or not) typically does. If every time you see a news report of a police officer killing someone, you come away thinking “police must just be killing people left and right”, you’re forming an inaccurate conclusion. If you get your news from anything that’s driven by attention/clicks (that is to say, approximately everywhere), it’s a doubly inaccurate conclusion.
