Sureshot, I really don't know why you make so many of these posts where you just post the first thing that comes to your mind diminishing the credibility you have.
If you took the time to watch the replay, snicko shows a CLEAR outside edge.
The edge is very small, and AMAZINGLY picked up by Aleem Dar.
Possibly the GREATEST ever umpiring decision of the century.
On hotspot, I believe Michael Atherton said that the white spot where the ball passed the bat was the sticker.
He was completely silent, when snicko showed that when the ball went past the edge of the bat, there was a big wave.
And the bat was NOWHERE near the pad. The bat did not hit the pitch.
Conclusion? The bat was right by the ball, and at the frame, snicko showed that Michael Vaughan indeed edged the ball.
Quite unsportsmanlike to act like he never edged it, and shake his head the entire time back to the pavillion.
Aleem Dar was and is an extraordinary umpire to pick that up.
