What exactly constitutes a "public airwave"?  Cops in the local county use
encrypted voice transmissions for tactical operations from time to time,
though the algorithm is trivial, it is still an encrypted communication.
Is there a set of spectrum in which such is allowed, or allowed for law
enforcement purposes?  (And no, I'm not referring to trunked comm.
systems).
