First, there have been lots of well written take downs of Charlie Gibson for the way he (or someone at ABC) did a hack job edit on the Gov Palin interview (like here. I'll leave that to everyone else.
I want to explain it. I think these folks at ABC learned how to edit an interview by watching the Simpsons.
Seriously, does anyone else remember the episode where Homer gets accused of sexual harrasment? (See here). There is a great scene where an interviewer edits his inteview with Homer to completely distort the message (the clock hands jumping all over are a great sight gag).
If they learned their journalism skills from this, it would explain so much...
