Hypo...Cyril Smith didn't get away with it because he was told old to be prosecuted. The investigations into him were called off by senior Police officers and security forces, because if he were taken to Court, he would have brought down a lot of other people with him. To put it bluntly, he knew where the bodies were buried.
This interference in the due process was totally unacceptable and its my belief is that it maybe still going on now.
I recommend anybody who hasn't read the following book, to do so....it will make the hair stand up on the back your head ::

But you are correct in what you say that historical child abuse isn't confined to the Tories....Smith himself was a Labour politician before he went over to the Liberals. Men from all Parties were involved. The guest list at the parties given at the Elm Guest House show a wide range of men, from lots of different backgrounds.
But unless we take heed of the mistakes of history, we are condemned to continue to repeat these mistakes for ever more.
