I realize reasonable doubt is only a legal standard, I was referring it to it because we are just assuming Pete Rose changed how he managed his based upon whether or not he had a bet on the game. Should we really ban him for life without solid evidence? As for the steroid apologists, its scientifically clear that taken them with make your stronger and therefor improve your athletic performance. I think it is also clear beyond a reasonable doubt Bonds and McGwire took steroids. McGwire admitted it. As for Bonds, all you have to do is take a look at pictures from when he began his career to when he was breaking records. Its pretty clear was on the juice. As for breaking baseballs most serious rule, shouldn't rules against cheating by taking drugs be just as serious?

I agree with what you say about the use of Rivera in your scenario, maybe Rose did this sort of thing, but maybe he didn't. How can you tell for certain that Rose did that kind of thing?
