Jon Christopher, of the West Yorkshire Police Federation, said people would ask precisely what was "going on" between Savile and senior police officers. He told BBC Breakfast:
I think people will look at it and think 'what is going on there?'. Because clearly he has been involved with a lot of officers and not just police officers, but other professionals as well.
Nevertheless, it's the police officers who are in the light with this one and clearly the lessons have to be learned from that, if he was under suspicion in other force areas that something could and should have been done at that time.
I think the problem we've got there is the people themselves will know what relationships they had and the extent of those relationships and if there is nothing recorded anywhere I think it is extremely difficult to prove otherwise.
