A most enjoyable Prize by Jack, not too difficult but, that said, some deviously tricky wordplay to keep us on our toes.
Actually, I say not too difficult but there is one clue (11a) which, apart from a 3 letter "crime" at the start, I can't parse at all and another where two answers seem to fit (8d), depending on whether the definition is "bill" or "Dawn's name".
I did wonder if the numerous mentions of terms such as police, courts, con artist, suspect in custody, material witness, prisoner etc. in the clues might be some sort of theme but, if there is, I can't see it.
Thanks to Jack for a good puzzle to kick off the weekend:-)
