Commission raises transparency concerns after Montgomery County Police encrypt dispatch communications

Members of the Advisory Commission on Public Safety raised concerns about Montgomery County Police’s recent move to encrypt radio and dispatch communications and asked for further briefing from the department on the rationale and public‑access implications.

Why it matters: Commissioners said immediate public awareness of ongoing police activity (road closures, active incidents) can be important for public safety and media reporting. Encryption of active dispatch channels could limit third‑party monitoring tools (scanners, Broadcastify) and raise questions about how the department will communicate time‑sensitive information to the public.

Susan (commission staff) summarized testimony from the work session: “MCPD has decided to encrypt its radio communications. Some of the radio communications for the special groups and discussion groups are already encrypted, but this would be, all of the communications between the the the police officers on the road and the dispatchers.” Commissioners raised competing concerns — preventing criminals from monitoring active police operations versus preserving timely public notice. Commission member Christina proposed a middle ground used in other jurisdictions: short, automated public alerts (for example, a brief text or social‑media post that a block is closed for police activity) so the public can avoid affected areas without exposing tactical details.

Several members asked staff to arrange a focused briefing from MPD so the commission can evaluate the policy’s public‑access and transparency implications and suggest mitigations (for example, proactive public notifications and published dispatch‑log release policies). The commission did not take a formal vote but instructed staff to pursue a targeted briefing and to share the MPD staff report and testimony in advance.
