You must know that unencrypted police radios have been a upstream source for local media for a long time, right?
And I’m not arguing that encryption is a good idea, in fact I think a blanket encryption of emergency radio is a bad idea (but nuance on social media is invisible).
This thread is simply in answer to an earlier poster who asked for a situation where it could be helpful to protect a sensitive situation and I provided one that we have seen analogs of in real life.
