It does seem likely. Only person that can confirm is Morrisey and I'm guessing close associates. How Saville got away with what he did is a scourge on those that were aware. Not unlike the investigations into grooming gangs. I reckon folk will be more prepared to come forward nowadays. Although hush money, job security, etc. Will still affect some.
That's a really big stretch. I don't think the Smiths would be scared of the BBC given that they didn't play their music much anyway. Plus, if it was then after his death and the revelations of sexual abuse they could have said something then Plus, they didn't why away from that subject matter with the song suffer little children.
Only guessing Helen, but the murderers were known. The fact that it wasn't widely known at the outset Saville was a paedo come sex offender. DJ Protected em from a lawsuit. Although I find it astonishing it wasn't brought out until after he died and the knighthood. I agree Morrisey ought to have revealed after he died and the investigations. But his mistrust of the media is well known.
