Apparently you either haven't read or choose to ignore the actual stats as to how many unarmed Blacks get killed by white cops in the US. Did you happen to see for instance the kid shot and killed in the park for instance. No justification whatsoever. Here are some stats for your edification.

Spare me. The stats aren't out of line with the stats on Black violence which causes a lot more interaction between police and, in particular, young black males. In New York city 56% of murder suspects are Black, as are 50% of
****, 66% of robberies, 70% of shootings, 53% of assaults, 57% of grand larcenies, etc. etc. The suspect stats exactly match the victim description stats so it's not like the cops are making stuff up. OF COURSE there's going to be a lot more violent interaction between police and the Black population on a statistical basis. BLM never talks about the Black crime stats but that's basically the reason.
Some years back Chris Rock did a funny video, an instructoinal video for Black men titled "How not to get your ass kicked by the POlice." Number one was "Obey the law".
