it happens in the field, and more upon when you find the opposite team, rather the batsman thrashing you all over the field, and you loose your cool. this was what happened to lara. the mr he-man, sent the ball over the places like firing bullets, and india gaining lead. lara did not had any options, as the replays were not clear, whether dhoni's catch was latched on clean inside the ropes by ganga, or not. he reacted teh other way, otherwise he (lara) too is a gentleman, a great player, but the deed was too unmanly. indians (specially dhoni and rahul) showed the spirit, by accepting and paying regards to lara's call. the truth still lies with ganga, who still is not sure whether he caught it clean or not, and then its lara who knows it well, what he did was correct or not.
