Verification Status

We do have per-talkgroup data for La Mesa 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 La Mesa 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.

Why do agencies like La Mesa 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 La Mesa Police to know what was happening nearby.

Can San Diego County reverse the encryption decision?

It can. The radios support open and encrypted operation equally well, so this is a configuration and a policy, not a constraint — and policies set by San Diego County officials are policies those officials can revisit when constituents press for it.

What can I do about La Mesa Police encryption?

File a FOIA request for La Mesa 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 San Diego 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.
