Yeah I agree that Michael will be 'safe' until he's done his 'job'
And yeah Sayid would probably have some form of publicity, but if there's no one there to take pictures of and perhaps the novelty of the OC6 has worn off by then.
Or maybe Ben faked Sayid's death to aid the 'hitman' thing, which would explain Mr Avellino's nerves when he told him who he was... but then people would recognise him...
