That can be done in a reasonable amount of time.
Cops in LA are also very highly paid especially in benefits and overtime. Part of the reason why they are so short staffed is that it is cheaper to pay a cop well into the 6 figures in over time and pay for one retirement pension then it is to hire two regular time cops and pay two pensions. I don't know how you fix this issue beyond enforcing stricter criminal punishment against bad cops and start actually busting heads instead of slapping wrists.

BLM doesn't form protests when black men are killed by black cops. They are politically savvy and understand that the optics of that aren't conducive to their message. In fact, they don't appear to care at all about non black people killed by police either. The 76 percent of people killed by police that aren't black don't interest them.
The real danger to black men in USA is being murdered by a non cop. Black men are insanely overrepresented in both homicide victimization and perpetration.
It should be noted that southern whites in the USA had massive rates of homicide until the early 20th century. They have significantly higher rates of violence compared to northern whites even today.

I don't know if this includes deaths by things like choking or beating.
If this is correct, death by cop is actually pretty rare. Not bitten by shark rare, but maybe in the magnitude of fatally falling off a ladder rare.
Which of course isn't to say harassment or abuse by cop is also rare. Nor to say there isn't racial disparity because the chart clearly shows there is.
That would indicate a leadership problem. Regular people just won't stay around when everyone from the top down is bent, even if the salary is outrageous.
So it’s around 20-100x more per capita than it could be.
In the United States when you look at the data that is posted in my previous comment you will see that the vast majority of police shootings involve an armed suspect.
However even if you only look at data on unarmed suspects I highly suspect that the US has a higher per capita rate than either Germany or Poland.
