I mostly agree, but I can also envision a situation in which you don’t want the people that you’re doing recognizance on covering up their illicit activities because they’re listening to the police radio. A good compromise would be to record the encrypted traffic and make it public some arbitrary but fair length of time after the fact.

What? Of course it should. Imagine if anyone doing ilegal activities were able to listen to police radio. Of course it should be private.
