Verification Status

We do have per-talkgroup data for Warren Police from the RadioReference API, and used it to set the encryption scope shown above — but no additional human-reviewed source (a live feed check or a dated news account) has been recorded for this record, so treat it as a data-quality correction rather than an independently confirmed verification. Check the live RadioReference database directly for current status.

If you monitor Warren Police directly or have more current information, the fastest way to fix this is to update the RadioReference Wiki entry — our data pulls from there and from the RadioReference API on a regular refresh cycle.

Frequently Asked Questions

Is Warren Police radio encrypted?

Warren Police is listed in our records with P25 DES-OFB encryption — a listing we haven't yet verified against live talkgroup data. This agency is listed in our database as encrypting all of its radio communications, including routine dispatch. The listing is unverified — confirm current status on the live RadioReference database.

Can I listen to Warren Police on a police scanner?

Likely not, if the listing is accurate: our database lists Warren Police as fully encrypted using P25 DES-OFB, which no consumer scanner can decode. The listing is unverified — check the live RadioReference database for current status.

Why do agencies like Warren Police encrypt their radio?

Ask why, and the answer is usually officer safety, sometimes operational security. What is harder to obtain is any documented case in Macomb County where an open channel caused harm. The costs need no such documentation: reporting on police department response slows down, and mutual-aid coordination gets more awkward, immediately.

Can Macomb County reverse the encryption decision?

Yes, and some departments already have. Because encryption here is a choice rather than a technical necessity, the path back runs through the same people who chose it: budget hearings, records requests, and residents who keep asking in public.

What can I do about Warren Police encryption?

Contact the officials who oversee Warren Police's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in Macomb County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
