Verification Status
We don't yet have per-talkgroup data for Coal City 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 low confidence (50%) based on how closely the wiki listing matches this agency's name and county.
If you monitor Coal City 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 Coal City Police radio encrypted?
Coal City Police is listed in our records with P25 AES-256 encryption — a listing we haven't yet verified against live talkgroup data. This agency is listed as encrypting specific talkgroups or channels, with other communications possibly still audible. The listing is unverified — confirm at RadioReference.
Can I listen to Coal City Police on a police scanner?
Possibly. Our database lists Coal City Police as encrypting specific talkgroups rather than the whole system, which would leave some channels accessible. The listing is unverified — check RadioReference for specific talkgroup status.
Why do agencies like Coal City 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 Grundy 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 Grundy County reverse the encryption decision?
Yes. Whoever made this call for Coal City Police can also unmake it; there's no technical lock-in. The approach that has worked elsewhere combines public-records requests, direct council pressure, and a coordinated local coalition.
What can I do about Coal City Police encryption?
Ask for the paperwork first — the policy that authorised encryption for Coal City Police, and the recordings themselves — because a specific request is harder to wave away than a general complaint. Then take what you learn to a council meeting, and bring others from Grundy County with you.
