I just noticed something when watching Return of the Jedi last night. Alright, so in the beginning, Luke sends the droids to convey his message to peaceably reason with Jabba in order to save Han Solo. He was announcing his arrival to bargain for Han. He shows good intentions. He's very polite and even gives the droids to Jabba. Obviously, the plan was to get rough if Jabba refused to return Han to them, but wasn't it a bit stupid to send Leia in there to steal Han before he even gets there? Wouldn't that destroy every single shred of credibility he was trying to build up?
