Qui Gon Jinn Possibly was a Sith Plant
I was thinking about this and I think that Qui Gon Jinn was part of Palpatine/Sidious' plan to kill the Jedi. If you think about it, Yoda couldn't tell Palpatine was infact evil. . . he even said it's hard to see the dark side. Qui Gon Jinn, after the council decided not to accept Anakin, was defiant and even stated he would train Anakin himself. Also, Qui Gon Jinn just didn't seem to be like the other Jedi, in fact he wasn't. . . he was more into going with ones own feelings, a trait that runs common in the dark side. This is further exemplified in Episode II when Count Dukoo/Darth Tyrannis reveals to Obi Wan that Qui Gon would have joined the sepratists cause if he had still been alive. It seems to me Qui Gon knew all along that Palpatine was Sidious and also knew of his overall plan. He forced the Jedi Council to accept Anakin so that they could train him in the ways of the force that would ultimately lead to their downfall.
