I think, ICC should take some reasonable action on this issue. Probably, the ICC action will show precautions to other player who are going to play for the forthcoming big event, world cup.
I fully concur with ICC to lay the charge even after Lehmann apologised. These are not small mistakes made inadvertantly. These come from deep rooted racial bias which is repulsive. Strong action is necessary if we really want to prevent such occurrences in future. Otherwise any body can make a remark like this and get away with it. It has always been happening and is bound to happen again otherwise.
