Oh, and I almost forgot. What right did Luke have to demand Chewbacca's release? Jabba paid for Chewbacca! Jabba paid one of Luke's operatives for Chewbacca. Assuming Leia didn't still have the credits on her when she was captured, would Luke have offered Jabba a refund? Probably not since he immediately came in with demands and mind tricks. Geez, is it just me or are the good guys, aside from being incredibly short-sighted and stupid, unnecessarily deceptive and underhanded?

Overall, I see it possible that someone might defend this by saying that they planned for the worst possible scenario. My rebuttal is that they only planned for the worst possible scenario... and the worst possible scenario in a very specific way. I mean, really, if any single thing had gone "right" in their plan, then they would have been screwed!
