Well, to be realistic, if Palpatine was willing to exterminate every single Gungan on Naboo, some backwater little planet in the middle of nowhere, what is the likelyhood that he would have tolerated a bunch of Ewoks within walking distance of his DS Shield Generator. Maybe he was getting mellow in his old age, but for someone who can foresee so many things, he should have been paying more attention to his back yard. Sometimes I get the feeling that Lucas was just a bit overwhelmed by the whole thing, and didn't pay a lot of attention to the actual story and whether or not it made sense. There are many examples that just don't sync up from one movie to the other, like Obi Wan saying he was trained by Yoda, when in fact it was Qui Gon, or like that whole thing with keeping the force in balance (see other thread). Oh well, Leia in slave clothes...
