Verification Status
We do have per-talkgroup data for Greenwich 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 Greenwich 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 Greenwich Police radio encrypted?
Our database lists Greenwich Police as using P25 AES-256 encryption, though this listing is unverified. Our records list a mix here: some talkgroups encrypted, others not. The listing is unverified, so confirm what is audible at RadioReference.
Can I listen to Greenwich Police on a police scanner?
Possibly. Our database lists Greenwich Police as encrypting some of its talkgroups while leaving others open, which would leave some channels accessible. The listing is unverified — check RadioReference for specific talkgroup status.
Why do agencies like Greenwich 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 Greenwich Police to know what was happening nearby.
Can Fairfield County reverse the encryption decision?
Yes — nothing about the underlying radio technology forces this. It's a decision Fairfield 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 Greenwich Police encryption?
Three things carry weight, in this order: a public-records request for Greenwich Police's encryption policy and radio recordings, a turn at the microphone during Fairfield County budget discussions, and finding the other people locally already asking the same question. Individually these are easy to deflect; together they are not.
