I say this story is an utter lie.
Don't you think it rather odd that there's been no other mention of this story in the press. No Muslim or human rights organisations calling foul, nothing mentioned in Parliament....
The Daily Mail is not a liberal newspaper, it's a sensationalist rag for the middle-classes in South East England to get worked up over the "injustices" of the world. They frequently misrepresent the facts and even lie, then let the story quietly drop.
It's a paper that is frequently quoted on American sites like this to "show" what Britain is like, with the inevitable outcome of Brit bashing carried out by many.
Well I guess the mystery of the head that told tales is come close to being solved.
