Here we go. From an Entertainment Weekly interview in 2004.
George Lucas: If you really look at it, there's hardly any changes at all. The thing that really caused the trouble on Star Wars is the whole question of whether Han Solo or Greedo shoots first. The way it got cobbled together at the time, it came off that [Han] fired first. He didn't fire first.
EW: So you consider this a correction?
GL: It's a correction. In my mind [Greedo] shot first or at the same time. We like to think of [Han Solo] as a murderer because that's hip -- I don't think that's a good thing for people. I mean, I don't see how you could redeem somebody who kills people in cold blood.
THIS MAKES NO SENSE. THE ENTIRE SERIES IS ABOUT THE FALL AND REDEMPTION OF ANAKIN SKYWALKER. AAAAAARGH.
If Vader can kill the Jedi, his wife, and even kill younglings(!), and then redeem himself and return to the light side by saving Luke, how the FUCK can Han Solo not be redeemed after shooting a guy who JUST SAID that he was about to kill him?
