Come of it.
This statement followed a re-look after the Labour Police Commissioner asked them to and even then they could only come up with a "might".
And they might have stopped him and if he'd said that he was driving to Barnard Castle for a walk along the river they would have had no grounds to ask him to return based on the CPS guidance put out early April after a host of examples of the police (particularly in Derbyshire) going too far.
So they might, but probably wouldn't have.
