He didn't need to stick out his hand as it was going straight to Dhoni and not hitting him anywhere. Decision has already been made so there is no point discussing.
Yes. And the point where he stops that throw is in front of his body and towards his right. If he had let it alone, the speed of the throw would have easily crossed Hussey and it was clear to the eye. If Inzamam was out obstructing the field in that game in Peshawar (there too, the throw was from Raina), then this was out too...
