Yet I can cite hundreds of cases of cheating in all the major sports in which, yes, there was a suspension or other penalty, but the players or people involved were then allowed to participate again. The examples you cited are very extreme, but even in these cases, they don't support your argument. None of those players were removed from the game during their playing careers and barred. And again, those are just the most extreme cases. There are many, many less severe cases, all of which support my argument and not yours. You might want to remove Schilling from your list, btw. He hasn't been accused of any cheating; instead, he did other embarrassing things.
