The way some FD's act on the radio in st clair county.... they need the encryption. A lot of the outlying departments including certain people in dispatch do not know how to be professional over a radio that tons of people could listen to. I love the scanner world but being a part of an agency in this county for 5 years has showed me that encryption is necessary. However other agencies across the country have their own reasons. Personally I think most FD's that go digital or are encrypted are talked into it by motorola salesman...
