Verification Status

We do have per-talkgroup data for Mount Pleasant 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 Mount Pleasant 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.

Shared Radio System

Why do agencies like Mount Pleasant 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 Isabella 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 Isabella 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 Isabella County officials are policies those officials can revisit when constituents press for it.

What can I do about Mount Pleasant Police encryption?

File a FOIA request for Mount Pleasant 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 Isabella 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.
