In reply to TobyA:
I went to see the reel rock tour on saturday past, and the final film is about this incident and includes clips of Jon Griffiths' footage taken during the actual incident.
This guy on reddit claims to have heard the details from a western guide who was on the rope fixing team- there was no western guide on the team involved, they were all Sherpa.
He also claims to have witnessed the follow up at camp 2 where a few Sherpa threw stones at Steck/Moro/Griffiths' tent- Having seen the footage of that part too, it was definitely more than a few! It was a baying mob 30-40 strong throwing stones, punches, kicks and spitting. Looked well hairy to me, and i'm a big hairy arsed ruffty tuffty Scotsman.
Incidentally, it turns out Steck and Moro's objective was a traverse of Everest via the west ridge and continuing over Lhotse without O2.
