He doped, he got suspended, served his ban and returned to racing. He's allowed to do so. Maybe the rule needs to be changed but until it is changed, it is the rule. Who's this Gambles dude to decide that such or such athlete is not welcome to race anymore? The "pro" thing to do would have been to accept the ruling of his governing body, suck it up and acknowledge the winner's victory. Then find means to make his opinion known, other than by shaming him on stage.

I'm all for tougher sentences towards dopers. But I don't think they should be ostracize or discriminated against beyond what the ruling called for.
