CSP sworn personnel were regulated and certified by the State's Department of Justice Commission On Peace Officer Standards and Training (POST). CSP officers were expected to, at any time, at any place, perform the same duties of any city, county or other state law enforcement personnel except those relating to custodial duties (jail/prison). As such, they were the State's oldest general law enforcement agency. Beyond the previously described duties, CSP personnel regularly served and executed State tax warrants, notices of seizure and maintained the peace (bailiff duties) in thousands of State Administrative Court hearings, meetings and procedures. The CSP regularly provided support personnel to other law enforcement agencies such as the State's Alcoholic Beverage Control (ABC), the State's Department of Justice Bureau of Narcotic Enforcement (BNE), State DMV investigations, Department of Health Services investigations, local law enforcement and coordinated State, Federal, Local Joint Agency Task Forces.
