Dr Paterson says Nisbett was still given opportunities to be alone with boys.

Insists there was no criminality in the report by Stuart Pearson, just a series of "inappropriate touchings" which he now understands to be grooming.

Dr Paterson thought Nisbett needed to be more careful. He thought Nisbett wouldn't do it again once he'd been caught.

Dr Peterson said at the time he believed offering boys cigarettes and alcohol was more serious than inappropriate touching. He says his views have changed.
