OAKLAND, Calif. (KGO) -- An Oakland police officer is in stable condition this afternoon with a gunshot wound to the leg, after an hours-long incident that began with a 911 call, led to a running gun battle and then a two-hour standoff at an apartment building just blocks from City Hall. It comes in a week when Oakland has already surpassed 100 homicides for the year.
