Re: For you - the pedantic types…
I think you guys give too much credit to conspiracy theories. First of all, Hawk Eye System is a technology used for review; the technology is not changed every time, depending on who the reviewer is. ICC (and other sports bodies inlcuing Tennis) decides to use that technology and when a review is aked for, this techonology is used to review with a third umpire to make a call based on the review.
Having said that, after watching the live appeal, my first instinct was that this was OUT. However, pleasant surprises happen.
