(Portland, OR)  --  Mayor Ted Wheeler is calling on the Portland Police Bureau to take more responsibility for the controversy surrounding its response to protesters in the city.  Wheeler spoke to KATU yesterday in response to comments from Portland Police Association President Daryl Turner, who said Wednesday he has no confidence in city leadership to deal with alleged looting and violence from groups of people using what he called "the cover of peaceful protests."  Wheeler says that comments like that demean the police bureau.  He added that at the end of the day, it's up to the bureau to "work together to resolve these issues as safely as possible."  Protesters have been demonstrating nearly every night in Portland for over a month, calling for an end to police brutality and systemic racism in law enforcement.
