OPS originated from the consolidation of various County departments' security forces. These Security Officers attained peace officer powers in the early 1970s, and were gradually retitled into Safety Police Officers. In the 1990s, the Department of Health Services Safety Police, the Parks & Recreation Department Park Police, and the Internal Services Department Safety Police were merged into the Office of Public Safety, which was unofficially known as the County Police. There were calls for OPS to be merged with the
Los Angeles County Sheriff's Department (LASD) in 1992 and 1997, The officers prevailed at trial, convincing a jury that the predominantly minority force had been denied appropriate pay and benefits due to racial discrimination, but the jury's decision was then reversed by the Appellate Court. The high court's refusal to hear a final appeal appeared to make a merger with LASD more likely, as they restarted their take-over study just days after the decision was handed down (September 20, 2007). Supervisor Knabe commented to local media the force should be disbanded for costing the County so much money. The merger study reports submitted to the Board of Supervisors served as a basis for what became a final decision about the proposed work place reduction. The Board of Supervisors set aside sufficient funding to complete work place reduction on September 22, 2009. On December 15, 2009, the Board of Supervisors voted 4–1 to eliminate OPS. The Sheriff's Department took over OPS responsibilities. After the Board of Supervisors voted to eliminate the OPS and turn its responsibilities over to LASD, all OPS employees were either hired by the LASD or placed on paid administrative leave by June 30, 2010, which was the target date set by the Board of Supervisors for its Human Resources to have placed the adversely affected employees in alternate jobs. Because few displaced OPS employees had actually been offered alternate employment by the target date, the Board of Supervisors extended the sunset period to September 30, 2010. Those deemed unqualified for alternate employment by that date were laid off. The former responsibilities of OPS are now handled by the newly formed LASD County Services Bureau and Parks Bureau. ==Leadership==
