Why do agencies like American Medical Response encrypt their radio?
Departments typically point to officer safety and operational security. Neither claim tends to come with evidence specific to Knox County; what's verifiable is what's lost — journalists can't monitor emergency medical services activity in real time, and coordination with agencies that stay unencrypted gets harder.
Can Knox 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 American Medical Response encryption?
Start local: show up when Knox County officials discuss the budget for American Medical Response, and ask specifically why full encryption was chosen over a delayed feed or tactical-only approach. File a FOIA request for recordings or policy documents, and connect with others nearby who want the same information — a coordinated ask carries more weight than an individual one.
