Statistics show that such a danger is very tiny compared to the benefit of seeking the aid of law enforcement for every race, even if you don't filter out cases where the officer was purposefully antagonized. Social media and 24/7 news is incentivized to publicize negative outliers. Similar to fear around radical terrorism - there is a pattern, but statistically it's not an issue worth altering your lifestyle around.
Which is only one part of my comment, and it's the one that (in my experience) people worry about the least (but it's always the one that people like to talk about the most).
What about the problem of police causing massive medical bills? What about the issue of fearing police involvement because they may charge you with a petty crime that can cause you significant issues? Or the worry that you could be arrested and jailed for having small amounts of marijuana which is legal just a few states over during an interaction with police? What about the worry of putting an office with their gun drawn in front of a suicidal person?
And even if none of that actually happens ever in "real life", the fear of it happening can be just as bad. It causes resentment, it causes kids to grow up fearing the police, it causes police to fear those who hate them, and instinctively act less friendly and helpful to them.
It's a problem that from where I'm standing looks like it can only get worse and worse. The police are no longer thought of as on "your side", and telling people that "statistically they aren't that likely to kill you" isn't going to solve anything.
I know a few cops, and they tell me that they don't worry about small amounts of weed (even though it's not legal here) because the local prosecutor doesn't want to bother with those cases. He has bigger fish to fry.
It's not that way everywhere, but many cops are going to look at the big picture and try to do what's "right" rather than be anal about arresting people for minor transgressions.
The discussion is largely rooted in anecdata and can be interpreted multiple ways due to the relatively low number of lethal events: https://www.washingtonpost.com/news/wonk/wp/2016/07/13/why-a...
