if the police were justified then thats sufficient
I didn't want to dig into it. Because quite often, the arbiter of whether police are "justified" is their own statements about the facts without the availability of body-camera or other corroboration. As I said, it's not a high bar to clear.
This isn't a racial question. I'm legitimately asking "why is it so much higher here?"
Maybe there's a valid explanation. We have tons of guns in this country, MUCH higher than most of those other listed countries, so it's possible that the majority of those police shootings were justified by the aggressive weapon-wielding actions of the person who was killed. I don't know.
Maybe Americans are, on average, just much more violent than people in those other countries and those were almost all legitimate instances of the person killed attacking the cops.
But much like the question about the US having the highest incarceration rate in the industrialized world, we're a SIGNIFICANT outlier here, and I'd like to know why. Maybe the answer is trigger-happy cops, regardless of whether they can string together facts that make the killings nominally "justified".
