Verified Talkgroup Data
Verification Status
We do have per-talkgroup data for Mount Pleasant 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 Mount Pleasant 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.

Frequently Asked Questions

Why do agencies like Mount Pleasant Police Department encrypt their radio?
Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to Charleston County; what's verifiable is what's lost — journalists can't monitor police department activity in real time, and coordination with agencies that stay unencrypted gets harder.
Can Charleston County reverse the encryption decision?
Yes. Encryption is a policy choice made by department leadership or elected officials, not a technical requirement, so it can be reversed the same way. Public pressure, city council advocacy, and organized local coalitions have reversed encryption decisions elsewhere.
What can I do about Mount Pleasant Police Department encryption?
Ask for the paperwork first — the policy that authorised encryption for Mount Pleasant Police Department, 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 Charleston County with you.
