Existing law establishes categories of peace officers with varying powers and authority to make arrests and carry firearms. Under existing law, in certain counties, including the Counties of Butte and Calaveras, a deputy sheriff, who is employed to perform duties exclusively or initially relating to custodial assignments with responsibilities for maintaining the operations of county custodial facilities, is a peace officer whose authority extends to any place in the state only while engaged in the performance of the duties of the officer's employment and for the purpose of carrying out the primary function of employment relating to the officer's custodial assignments, or when performing other law enforcement duties directed by the officer's employing agency during a local state of emergency. This bill would include a deputy sheriff employed by the County of Fresno or the County of San Joaquin within that definition of peace officer. The bill would make related findings and declarations.
