Apples and truck comparison.
Rhodesia and South Africa have been 90% + black for several generations. Blacks in America? 15%....and if you take out women, children, elderly, disabled, and incarcerated, you have <5% of the US population. THink the Latinos, Native Americans, Rednecks, and Orientals will roll over for them? Never.

The real risk is probably 2% of the population—16-30 year old males, and probably only half of them.
That is why “racial profiling” was a thing—while it may have been unfair from time to time the benefits to society as a whole were very significant.
