Verification Status

We do have per-talkgroup data for Brea 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 Brea 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

Why do agencies like Brea Police encrypt their radio?

Agencies cite officer safety and operational security. Those are assertions rather than findings — no local evidence is typically produced — while the effects are concrete and land straight away on anyone who relied on hearing Brea Police to know what was happening nearby.

Can Orange County reverse the encryption decision?

Yes — nothing about the underlying radio technology forces this. It's a decision Orange County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.

What can I do about Brea Police encryption?

File a FOIA request for Brea Police's radio recordings and encryption-decision paperwork, then show up to speak at a council or commission meeting. Find other residents or journalists in Orange County who want the same access — state legislation requiring public radio access is the longer-term fix, but organized local pressure is what usually moves the needle first.
