Decision review system is good to implement in india.but the issue is the cricket fans r so crazy for indian victory that they immegiately by observing the screen shout that umpires decision is against indian batsman and than batsman can go for DRS.It is nice to read that the CEC had said it was satisfied with the improvements in technology in the DRS, which included new Hot Spot cameras and independent ball-tracking research.Umpires r human being and might error in decision making.The limit is given to each side.so how to use the allauddin ka chirag wish is on cicketers.In fact the system is currently used in England vs westindies.It is all on icc and BCCI to decide.
