Also experts asked by the BBC say that this is a very bold statement;
Prof. Paddy Regan, says:
"They are saying the hypothesis that Arafat was poisoned with polonium-210 is valid and has not been disproven by the data. However they cannot say definitively that he was murdered.
Prof Regan says a series of assumptions would have been made in order to ascertain how much Po-210 may or may not have been in Mr Arafat's body at the time of his death."
'has not been disproven' - means it has not been proven either. No?
