It is Official: Early Draft of Star Wars Says Han Shot First

Well, I could have told you this.

It is difficult to tell whether Han or Greedo got the first shot in, and several updated versions of the film haven't helped to settle the debate once and for all. For instance, in the 1997 version, the scene was slightly altered to make it look as if Han was acting in self-defense. 

"I'll tell you one thing, right now," Brown told CBC, "Based on the script, I can tell you 100 per cent, Han shot first."

Han shooting first makes him a badass smuggler. So when he becomes heroic later in the story his transformation is even better. Having Greedo shoot first (and miss at point blank range) was such a cop-out. That is what made the 1976 George Lucas a genius while the 1997 Lucas was just a hack resting on his laurels.
