Long before encrypted systems became ubiquitous (let's call it 1980s/90s), PDs used Nextel PTT, then cell phones, and now MDTs to transmit sensitive info. I really don't get the point of encryption on general dispatch channels. I think the next step in this cat and mouse game is going to be people using their drones to monitor police activity and then tell the world about it via social media as it's happening. Still not as good as being able to listen in directly, but enough to annoy public safety wishing to hide their CFSes via encryption. CSP probably goes full time encrypted in the near future which means law enforcement monitoring is no longer a thing in CT given that CSP is the primary law enforcement agency in most of the state.
