MO HB2789

Uniformed law enforcement officers must wear operating video cameras with audio microphones at all times when interacting with the public in their official capacity, with all recordings catalogued and preserved

Police vehicles primarily used for traffic stops must be equipped with video cameras, with 50% compliance required by June 30, 2016 and 100% by December 31, 2016

Police departments must maintain written policies covering camera activation requirements, disciplinary actions for non-compliance, minimum 30-day retention periods for recordings, and equipment replacement procedures

Officers must notify individuals they are being recorded, and recording is prohibited inside private residences; exemptions apply to undercover officers and situations where cameras would endanger safety

In prosecutions, defendants can request copies of required recordings, and courts may draw adverse inferences against the state if recordings are not produced
