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.]

Completely outside of my area of expertise, so this may be a silly question, but are police transmissions distinguishable from others in their encrypted form? If so, there could still be a use case for knowing _where_ the cops are. Wonder if some sort of mesh could be used to triangulate the positions of these signals.

Outside of my area as well, but, IIRC Kevin Mitnick wrote about using a radio set to encrypted frequencies. When he was out and about, if he heard traffic on those frequencies, then he knew the FBI etc. must be nearby.
