The gist of your answer implies that you believe Moggi is guilty. Your analogy has little relevance to the point you're trying to make.
If Moggi is guilty, then it follows that Juventus is also guilty. Although Moggi may have committed some sort of wrong, the wrong was common practice amongst all teams, not exceptional, and so, Moggi's so-called wrongdoing was used to brutally bring this entire club down in the most of heinous of ways.
That is why we all defend Moggi. Rather than the FIGC cleaning up the entire league, they found a scapegoat, Moggi and Juventus. The FIGC, and Italy as a whole, is littered with corruption. We, Juventus, club and fans, should not sit down while our name is being unjustly dragged through the mud. We are a proud club that is the epitome of success in Italian, European and even world football. We have won many titles and have had some of the most celebrated players don our jersey.
At this time, Moggi seems to be the only one interested in putting his money where his mouth is and defending this club in any manner possible.
