Requires that a behavioral health specialist be dispatched with law enforcement when responding to calls classified by dispatch as mental-health related

HB 3131 requires that for all emergency calls classified as mental-health related, law enforcement must respond with a behavioral health specialist (such as a psychologist, social worker, or counselor) alongside the officer. This applies unless dispatch or on-scene assessment indicates an immediate threat of violence, in which case officers may initially secure the scene without the specialist but must bring them in once the scene is safe. The bill mandates standardized dispatch protocols to identify mental-health calls and assign co-response teams, directly affecting Missouri law enforcement agencies and emergency dispatch centers. It aims to improve crisis response by ensuring trained behavioral health professionals are part of the initial emergency team for mental health calls.
