Why did McHenry County - Southeast Emergency Communications Center encrypt their radio?

Can McHenry 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 McHenry County - Southeast Emergency Communications Center encryption?
Contact the officials who oversee McHenry County - Southeast Emergency Communications Center's budget directly and ask why full encryption was chosen over partial alternatives. Pair that with a FOIA request for recordings and policy records, and look for an existing coalition in McHenry County, or start one, since agencies respond differently to organized, sustained pressure than to individual complaints.
