If you re-watch this so-called "unedited clip", the crowd were CHEERING when the judges gave their scores. Every single scores, the crowd were cheering.
However, as Sarah Palin WALKED onto the ballroom floor, the crowd started to BOO Sarah Palin. If you look at the crowd behind the judges, they were all looking in the direction Sarah Palin was sitting. You can then see that one the guy ran to Sara Palin and that's when Sara started to speak.
Of course the crowd were all TOLD to cheer when Sarah began to speak.
What's also interesting? The West Coast viewers received an EDITED version of the clip ABC aired in the East Coast showing Sara Palin after the "booing". Anyone who was ACTUALLY was actually at the taping want to comment?
Why would the crowd wait until the LAST "EIGHT" to start booing? My guess is, Sarah Palin walked onto the Dance Floor while Bruno was giving his score and that's when the crowd started to boo Sarah. You can even see the commentator run to Sarah Palin while the crowd was booing.
