David Oh, the Republican candidate for mayor of Philadelphia, shared how years of failed city policies have eliminated police officers' power in Kensington. WARNING: This story contains graphic images. PHILADELPHIA -- David Oh is frustrated with widespread, open-air drug use and high crime in the Kensington neighborhood. That's why the mayoral nominee has formed a plan aiming to clean up the streets and to save and protect its residents, helpless to stop addicts from stumbling through the streets in a stupor. "If we get rid of Kensington Avenue as a place that exists in this region, the better off people will be," Oh, a Republican, said.
