Verified Talkgroup Data
Verification Status
We do have per-talkgroup data for City of Joliet Police Department from the RadioReference API, and used it to correct this listing’s encryption status — 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 City of Joliet Police Department 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 City of Joliet Police Department encrypt their radio?
The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.
Can Will County reverse the encryption decision?
Yes — nothing about the underlying radio technology forces this. It's a decision Will County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.
