dhoni a Gentleman or cheater ?

I dont know what Indians think about their captain’s on-field behavior in the second last match of the super 4 stage in the Asia CUP. Towards the end of Srilankan inning Tilan Thushara was given RUNOUT by the 3rd umpire when the video replays clearly showed Dhoni messed up with the runout. The important question is whether Dhoni knew what happened ? and if so, what does this say about Indian captain’s spirit of the game ? this situation can be compared with the recent Sidebottom controversy in England. Another aspect to this incident in the Asia cup is that whether Dhoni really appealed for the runout ?  or can the umpire refer the decision to the 3rd umpire without the appeal from the fielding team ? well, I dont think that can happen. In any case, Dhoni’s silence really dont go good with the spirit of the game.
