Why did Washtenaw County Sheriff encrypt their radio?
The reasons offered are almost always the same two: officer safety and operational security.

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