About ten years ago I had to drive over there from San Francisco to pick my husband up at the Oakland airport ... at night time, took the wrong turn off and had to drive city streets to the airport, stopped at a service station for instructions and was stunned to see they had police guards at local gas stations after dark... Jerry Brown did nothing as mayor to make Oakland better, if anything it got worse (from my viewpoint) under him.
I know that area well. It is not safe to drive some of those city streets, especially if driving while white.
