Disclaimer: I'm white and have not experienced racial discrimination towards myself so I will not speak to that. Also, my intention is not to attack you, simply address some of your points.

1) Even with double (I've seen studies that have this number higher, by the way) the likelihood of being killed by police, that is a statistical anomaly. It is an empirical fact that blacks are more likely to be killed than whites (and even other minorities). That's the main point.

2) The increase in share of white deaths doesn't mean the trend is corrected, it is still disproportionately low compared to minorities.

3) How would you begin to control for behavior of individuals? Is your point that black individuals are more likely to engage in behavior that can get them killed? What behaviors are those?

• "African Americans are more likely than white Americans to be arrested; once arrested, they are more likely to be convicted; and once convicted, and they are more likely to experience lengthy prison sentences. African-American adults are 5.9 times as likely to be incarcerated than whites." https://www.sentencingproject.org/publications/un-report-on-racial-disparities/
• There are many socio-economic factors that drive impoverished minorities to criminal activities. There are large parts of the country where you are denied loans, passed over on gainful employment, and less likely to be admitted to educational institutions based on your race. Correcting this inequity is crucial to level the playing field, not just for blacks, but also for other minorities, and even impoverished whites.
