Monrovia Police
Los Angeles, California
How we verified this
The listed 'all operations AES-256' claim is unsupported: the ICI system page has no Monrovia police talkgroups (only MRV FD ADMIN fire), and RR's Monrovia page lists MRV PD1 dispatch and PD2-4 tacticals as clear analog FMN/FM with PL tones — confidence medium since the analog listing could be stale and no live feed was found to prove current clear traffic.

Frequently Asked Questions

No. Despite earlier listings, Monrovia Police broadcasts in the clear. This agency was previously listed as encrypted, but verification against live sources on 2026-08-01 found its dispatch broadcasting in the clear. Any P25-capable scanner can receive it — confirm current status on the live RadioReference database, since encryption decisions can change.

Why do agencies like Monrovia Police encrypt their radio?
Officer safety and operational security are the reasons agencies give. What rarely comes with that explanation is Los Angeles County-specific evidence that open communications ever caused a problem, while the loss of public oversight and the friction with still-unencrypted neighboring agencies are both immediate and real.
Can Los Angeles County reverse the encryption decision?
Yes. Encryption is a policy choice made by department leadership or elected officials, not a technical requirement, so it can be reversed the same way. Public pressure, city council advocacy, and organized local coalitions have reversed encryption decisions elsewhere.
What can I do about Monrovia Police encryption?
Start local: show up when Los Angeles County officials discuss the budget for Monrovia Police, and ask specifically why full encryption was chosen over a delayed feed or tactical-only approach. File a FOIA request for recordings or policy documents, and connect with others nearby who want the same information — a coordinated ask carries more weight than an individual one.
