In Oakland, California police arrested 152 people Friday night after hundreds took to the streets to protest what they viewed as the lenient sentencing of the BART police officer who shot dead Oscar Grant two years ago on a train platform. The officer, Johannes Mehserle, was sentenced to two years in prison, the shortest sentence he could have received. In July a jury in Los Angeles convicted Mehserle of involuntary manslaughter, but acquitted him on the more serious charges of second-degree murder and voluntary manslaughter.
