In Revenge of the Sith, I noticed the Jedi had several chances to defeat the Chancellor. Here's a list Red Letter Media put together: 1. Tell Palpatine to step down, if he doen't tell him why he is so qualified to conduct a war. 2. Use Process against him, have Bail Organa call for a vote of no confidence in Palpatine, if Palpatine says no, he'd be fighting for an unlimited term for no good reason. 3. Look more thourgohly into where the Clone Army came from. 4. Look into his heart, if he can block you, he may know the ways of the force; speciafally the Dark Side. 5. As I mentioned earlier, check his Midi-Chlorian count. 6. Physically confront him in public, if he runs of attacks, he'd be exposed 7. Blantant Evidence, show Senate the Jedi Temple Security tapes while the Senate is in session. 8. If all else fails, Obi-Wan and Yoda team up to kill the Emperor, then then kill Anakin. So my question is, how could the Jedi not see any of these points?
