Second place? Marin.
Do take time to peruse the entire report, "The War on Marijuana in Black and White: Billions of Dollars Wasted on Racially Biased Arrests." The ACLU went through arrests rates in each 50 states, county-by-county, and found:
"In over 96% of counties with more than 30,000 population in which at least 2% of the residents are Black, Blacks are arrested at higher rates than whites for marijuana possession," the report found.
In California, five counties had racially disparate arrest figures above that national average: San Francisco, Marin, Lake, Sacramento and Kern counties, according to the report. And San Francisco and Marin have the most racially disparate numbers, with 192 African-Americans arrested for weed for every 44 Caucasians in San Francisco, and 507 African-Americans arrested for every 123 Caucasians in Marin.
The numbers in San Francisco are staggering -- and all the more so when you consider that there aren't very many African-Americans left in San Francisco.
African-Americans constitute about 6.3 percent of the population in San Francisco, according to Census figures. Caucasians make up about 42 percent of San Francisco. So there are five times as many Caucasians than African-Americans in San Francisco -- yet there are four times as many black people arrested for weed than white people.
At least the cops no longer use those fire hoses and dogs on African-Americans.
