It could take at least six months for the FBI to determine whether Minneapolis police officers used force appropriately in a February traffic stop. Police Chief Tim Dolan asked the FBI to review the case after he watchied a video depicting the traffic stop. At one point the squad car camera shows several officers kicking and punching 42-year-old Derryl Jenkins as he is lying on his stomach in a snowbank. Officers claimed Jenkins was speeding and that he fought with officers. But those charges were later dropped. And Jenkins' lawyer has not ruled out suing the police department. Chief Dolan says the arresting officer, Richard Walker, found himself in a difficult situation.
