I also have no problem with players and owners being slammed in the court of public opinion, and I hope what happened to McGwire (rejection in his first Hall of Fame vote) is repeated many times.

Judge the ones who did, sure, if you know for sure that they did, based on their own admissions or clear documentary evidence. But, what about the ones where there's suspicion but no smoking gun. And, for what it's worth, right now there's more compelling evidence against Paul Lo Duca than against Mark McGwire.
