No, I was referring to Morse which some people wrongly call a code i.e. Morse code. It's another language really. I then got the very witty answer that the Police don't use Morse any more because he is dead (Inspector Morse of TV fame). Okay?
Ello ello ello, listening to police radio is an offence and not to be admitted!
No.
Only if you "make use of it". I.e, a jpournalist using a police scanner to "get to the story first", or a thief using it to know if "the area is clear".
