"The problem is that radio stations typically don't have anyone in the booth most of the time, if ever:" Agreed, it's a serious issue, and the first thing one notices about prerecorded and netwoked programs is the lack of spontaneity and liveliness of the content (personally I don't like stations that are run like this).

There's no reason why programs cannot be interrupted by an actual human in such emergencies, even if not a professional announcer, an emergency worker or police perhaps.
