Verification Status

We don't yet have per-talkgroup data for Des Peres Police from the RadioReference API. The encryption scope and type above come from the RadioReference Wiki, which is community-maintained rather than independently confirmed channel-by-channel. Our automated matching put this at moderate confidence (70%) based on how closely the wiki listing matches this agency's name and county.

If you monitor Des Peres 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.

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 Des Peres Police to know what was happening nearby.

Can St. Louis 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 St. Louis County officials are policies those officials can revisit when constituents press for it.

File a FOIA request for Des Peres 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 St. Louis 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.
