Existing law requires each law enforcement agency, on or before January 1, 2021, to maintain a policy that provides a minimum standard on the use of force. Existing law requires that the policy include, among other things, training standards and requirements relating to demonstrated knowledge and understanding of the law enforcement agency's use of force policy by officers, investigators, and supervisors. Existing law prohibits a law enforcement agency from authorizing the use of a carotid restraint or choke hold by any peace officer employed by that agency. This bill would, until January 1, 2030, prohibit a law enforcement agency, including a federal law enforcement agency, from using a wearable electroshock device within the State of California. The bill would also prohibit a law enforcement agency from using state funds to purchase a wearable electroshock device. The bill would require a law enforcement agency to update their use of force policies to prohibit the use of a wearable electroshock device. By increasing the duties on local law enforcement, the bill would impose a state-mandated local program. The bill would require the Division of Law Enforcement within the Department of Justice to conduct a study on the safety and community impacts of wearable electroshock devices and provide recommendations for appropriate standards and safeguards for their use, and would require the department to report to the Legislature on the findings and recommendations of the study on or before January 1, 2029. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
