Townshend was arrested in 2003 after accessing a child porn website to research a book he was writing, but Daltrey insists the guitar hero was always innocent.
He says, "It's tragic what we are prepared to do to good people.
"Pete was stupid - he said that from day one - but he hadn't done anything.
"I would have been the first to say if Pete had done anything, throw the book at him. But there was nothing there."
