Oakland's top cop defends force • Oakland's police chief on Friday defended officers involved in a clash with anti-Wall Street protesters, saying they used what they believed to be the least amount of force possible to protect themselves. Interim Chief Howard Jordan said he took full responsibility for the actions of his officers, whom protesters accused of injuring an Iraq war veteran during the clash Tuesday night. Scott Olsen, 24, remained hospitalized in fair condition with a fractured skull after police fired an object that struck him in the head, fellow veterans said.
