(Portland, OR) -- Despite his previous defense of the response by Portland police to violent protests last summer, Mayor Ted Wheeler says mistakes were made.  He now says there may be changes made in how police respond to political violence in the future.  The clash between the far-right group -- the Proud boys -- and the so-called antifa, a far-left group -- resulted in fights and explosives being set off near businesses.  Before the protests, Mayor Wheeler had said police would take a hands-off approach to dealing with protesters.  Yesterday, during the City Council's weekly meeting, Mayor Wheeler admitted that approach was a mistake.
