Is Jefferson County Sheriff's Office radio encrypted?

Why did Jefferson County Sheriff's Office encrypt their radio?

Can Jefferson County reverse the encryption decision?
Yes — nothing about the underlying radio technology forces this. It's a decision Jefferson County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.
What can I do about Jefferson County Sheriff's Office encryption?

File for the recordings and the decision documents alongside it, and link up with neighbours and local reporters in Jefferson County so the ask arrives as a group rather than a one-off.
