I think there is some filtering of what is and what is not used for outrage. The fact is it's fairly shocking how many people cops kill every year regardless of race. 240 people have been shot and killed by police so far this year and that's with people sheltering in place for months. Don't have stats for people who die in custody or recently after interacting with the police, and that 240 doesn't include cops killing people without shooting them. I really do think there is an aspect of what sells in choosing which stories get a boost.
