I completely agree, as I said earlier a two time cheat should be nowhere near a world event. I was responding to the suggestion that a first time cheat should never compete again.
I understand why you have that view but people do make one off mistakes and can reform and do good for their sport - David Millar in cycling as an example.
I think there is a case that a first time cheat should potentially be given a second chance but a two time cheat should not be anywhere near the world stage again.
