Encryption Details
Verified Talkgroup Data
Verification Status
We don't yet have per-talkgroup data for Marshall 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 (60%) based on how closely the wiki listing matches this agency's name and county.
If you monitor Marshall 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.
Calhoun County Context
Marshall Police isn't an outlier here: 5 of the 5 public-safety agencies we track in Calhoun County are fully encrypted (100%), so most departments nearby have made the same move.

Why do agencies like Marshall Police encrypt their radio?
The reasons offered are almost always the same two: officer safety and operational security. Whether either was tested against a real Calhoun County incident is rarely part of the public record, whereas the consequences are easy to observe — no real-time accountability, and neighbouring agencies still in the clear left working around the gap.
Can Calhoun County reverse the encryption decision?
Nothing technical prevents it. Marshall Police operates encrypted because someone decided it should, and decisions of that kind get revisited when councils hear sustained, organised pressure rather than isolated complaints.
What can I do about Marshall Police encryption?
File a FOIA request for Marshall 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 Calhoun 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.
