Wow, I had no idea Lucas was making that claim. I just assumed he changed it in the SE to make it a bit more kid-friendly.
Duh... I probably first saw SW when I was 3 in 1980 and I never once thought Han was a bad guy because he shot Greedo. As a kid that young even I figured out that Greedo was trying to kill him. Give kids some credit.
This is so stupid to me. First of all, how is this a debate? Until the special edition, Han shoots and kills Greedo before Greedo can get off a shot, period. Early drafts of the movie are just that, early drafts. All sorts of things change from one draft to the next, and even while filming. The only thing that matters is what ends up on the screen, and not what ends up on the screen when the director decides to go back and bastardize the original film.
This was never even open for debate.
