Let’s see, what have we got? Politicians lying, cheating and touching each other inappropriately. Senior police officers selling information and lying. High-ranking church figures abusing children. I could go on and include sports personalities and television presenters, but the point has been made.

People ask me why I chose to spend most of my career in the company of children in pupil referral units. I did so because their moral code is, in general, more reliable than many of the above with all their advantages of education and upbringing.
