SAN DIEGO — Community leaders on Wednesday urged the county Board of Supervisors to pass an anticipated resolution in support of a sweeping federal police reform bill named after George Floyd. “I call on our supervisors to do what is right,” the Rev. Shane Harris, a civil rights activist, said during a news conference outside the County Administration Building. The Board of Supervisors will decide Tuesday whether to direct the chief administrative officer to support the George Floyd Justice in Policing Act on the county’s behalf. Among several reforms, the legislation would ban chokeholds, racial profiling and qualified immunity, a court-established concept that shields police officers and other government officials from lawsuits except in cases in which officials violate “clearly established” constitutional rights.
