Perfect game blame

I can't believe the firestorm raping Jim Joyce over his missed call. Jim Joyce doesn't have instant replay at 1/30 the game speed which it occurred at. He made a mistake and he's admitted such. I saw it live and started to celebrate and think to myself how cool it was I saw the 9th inning of a perfect game when it all fell apart. Galarraga handled it well, as did Leyland during the post-game interview. I'm all for instant replay but I am the farthest thing from OK with allowing previous rulings to be overturned. That is asking for a world of hurt. Everyone knows Galarraga had a perfect game and history will reflect that he came within one out that he actually got fair & square of a perfect game. Blown call in a big moment, we've seen this before. Explain to me how Derek Fisher got off a running jumper with .4 seconds on the clock? Or the Kordell Stewart scamper vs. the Colts in the AFC Championship game where he stepped out of bounds? Bottom line: You can't change the past, it's opening Pandora's Box and that's never been a good thing.
