I think he was out. Since Hawkeye is dependent upon the person operating the technology foul play should be not be ruled out. Im sure some indian guy running the software quickly made some changes so their "God" sachin would not fall to a brilliantly disguised arm ball by Ajmal. Ajmal himself claims not to understand what happens as he bowled the straighter one which should have gone on to hit the stumps. In my opinion ICC needs to stipulate that all persons running the review technology be neutrals just like it mandates having neutral umpires in all international games.

the defining moment of the world cup.loved to see ian gould's reaction after his shock that a plumb decision got overturned.
