Security police powers and authority
Security police differ from
security guards in that personnel of security police agencies are considered
law enforcement officers, while security guards generally are not. Even where security guards hold some form of policing powers beyond that of the average individual they are not generally considered "security police." The powers and authority of security police vary by jurisdiction, but at a minimum they generally hold detainment and arrest powers.
Some security police agencies enjoy enhanced authority in certain circumstances. For example, the

Security guards (including off duty peace officers) may only carry firearms in private employment if licensed by the state licensing authority, the
Bureau of Security and Investigative Services. Persons regularly employed by public agencies as security guards, however, may be exempt from BSIS regulation, if they have completed POST-certified training in accordance with PC 832 or other penal code sections. However, security guards employed by a private employer are still regulated by BSIS even though the client may be a public agency.
Orange County
Orange County Sheriff's Department special officers (SSOs) are duly-appointed California "public officers," defined b
''California Penal Code (PC) 836.5'' which grants public officers the authority to "...arrest a person without a warrant whenever the officer or employee has reasonable cause to believe that the person to be arrested has committed a misdemeanor in the presence of the officer or employee that is a violation of a statute or ordinance that the officer or employee has the duty to enforce." The statute additionally grants them powers to write summons and tickets.
SSOs are designated public officers by
California PC section 831.4. (a) (1)'. This statute additionally authorizes them to carry firearms in the course of their duties. SSOs provide citation enforcement and general security and law enforcement services for the department in connection with the county

SSOs attend a 16-week training academy at the Orange County Sheriff's Regional Training Academy that instructs new officers on laws of arrest, firearms training, arrest and control techniques, physical fitness, field and patrol tactics, first responder medical training, and corrections-custody training.
From 2016 to 2020, their right to carry concealed off-duty under their employment status was stripped. However, in December 2020, a agreement was brokered between the OCSD sheriff and the SSOs' union; SSOs would be provided identification cards identical to "sworn OCSD deputy sheriffs" which would identify them as either "law enforcement" or as "honorably retired law enforcement," as appropriate, and would identify them as personnel with "statutory arrest authority." While this would not confer upon SSOs California peace officer status, nor would it permit them to carry concealed off-duty under the color of California law, it would technically permit them to carry concealed off-duty under federal law (
LEOSA), as their new identification cards meets the requirement to carry under the auspices of LESOA.
