Most of our local departments use encrypted radios.
"Over the past few years, an increasing number of municipalities and police departments, including the District’s, have begun encrypting their radioed communications.."[1.]

What I heard is many police departments now encrypt their radio communications, with the exception of dispatch which they keep in the clear as a concession to the media and ambulance chasers.
