My father was a policeman and rose to Sergeant in a lot less time than Dan has been in the force. He left because, years ago, pay was not as good as now and he had major expenses....... e.g. me!
But he lined up a well-paid job in the private sector berfore he left.
Dan's hasty departure from the police has more to it than meets the eye. I don't buy the Savile investigation excuse.
