SAN FRANCISCO (KCBS)  -- The number of African Americans in San Francisco jail is growing steadily while the number of black residents in the city is shrinking, according to Sheriff Michael Hennessey.

About 42 percent of the jail population is in custody on drug charges, he said. Meanwhile, only 6.7 percent of the residents in the city are black. [MORE]
