The overall population of whites in the nation is about 62%, whereas the overall population of blacks in the nation is about 14.8% to 15%. Based upon the much larger population, it is natural for the number of whites to be arrested to be higher than the blacks.
That said, inner-city blacks commit the majority of crimes in the major metropolitan areas. Instead of staying out of trouble and focusing on education and personal achievement, they blame others for their joining criminal gangs, drug dealing, thefts, robberies, home-invasions and murder. There are plenty of blacks that succeeded even though they grew up in the inner-cities. Even actual black Africans that immigrate here have no respect for the negative culture inner-city blacks. For while the negative culture inner-city blacks are pointing the blame at others, mostly whites, for their failures, the actual Africans are making money and achieving success.
Stop being a Marxist seeking to divide this nation and stop promoting the fake narrative that it's the white peoples fault. This is a free-market capitalist nation with basic freedoms tossed in by our Constitution and capitalism is color-blind, outside the color of money.
