Still not sure what happened?

The BBC report that 'Gaza flotilla was Turkish provocation: Livni to inquiry'. As one would expect the article takes an opposite view. I particularly liked this sentence:

'Israel says its soldiers fired in self-defence after they were attacked with clubs and knives, but activists say the Israeli commandos opened fire as soon as they rappelled from helicopters on to the Mavi Marmara's deck in international waters.'

Have the BBC not got access to the videos showing that what Israel said happened, did happen? Are the BBC so anti-Israel that they prefer to push a demonstrably incorrect 'narrative' rather than report the truth?
