Does the police in the US kill more white or black people every year? They kill more white people, in absolute figures. So then you say "but whites are a higher proportion of the population than blacks, hence blacks are killed at a higher rate". Yes, but who proportionately has the highest crime rates in the US?
Regarding "protest", I am all in favor of peaceful protest (which most of BLM protests were, let me emphasize this!) but not in favor of violent protests. I hope you feel the same.
