Why do agencies like Sullivan County Volunteer Fire Department encrypt their radio?

Can Sullivan County reverse the encryption decision?

Yes, and some departments already have. Because encryption here is a choice rather than a technical necessity, the path back runs through the same people who chose it: budget hearings, records requests, and residents who keep asking in public.

What can I do about Sullivan County Volunteer Fire Department encryption?

Ask for the paperwork first — the policy that authorised encryption for Sullivan County Volunteer Fire Department, and the recordings themselves — because a specific request is harder to wave away than a general complaint.
