The bill amends Chapter 6A of the Massachusetts General Laws to establish protections for the privacy of individuals who place calls to the 911 system. It introduces Section 18M, which designates audio or video recordings of 911 calls as private data concerning the caller, while allowing for the creation of public written transcripts upon request. The requester must cover the actual costs associated with transcribing the call. The bill permits the dissemination of audio recordings to law enforcement for investigative purposes and allows their use in public safety and emergency medical training.

Furthermore, the bill prohibits the release of 911 audio recordings without the express written consent of the caller or their legal representative, except in cases where a court order determines that public interest in the recording outweighs the caller's privacy rights. However, this privacy protection does not extend to law enforcement personnel conducting investigations where the 911 call may be relevant.
