I have no claim, I have no idea what happened, but I do know that video footage of prison cells where prisoners killed themselves does does not disappear by accident, saying it dies in such a high profile case alone requires quite a high burden of proof (I.e, the prison burned down, there was an unexpected solar storm). If there is no obvious explanation, the most likely one is it was deleted deliberately.

How do you know that?
To me, this is like saying "backups of important data do not become unrecoverable by accident." Except backups (and CCTV footage) is routine, high data volume, and very usually uninteresting, so something going wrong can very easily be missed. And things can go wrong with relatively high frequency--I would not be surprised if most attempts to restore from backups failed.
