I watched the movie tonight, and I came to the same conclusion for different reasons.
We have ‘The Republic’ which te Jedi know to be corrupt, which has proven it is unable or unwilling to protect its citizens from being slaughtered and enslaved (see Naboo invasion TPM). In short it is failing. A group of people wish to leave this ‘Democracy’. They don’t want to orchestrate a coup. They want to leave. And the Jedi are forcing them to stay why? Aren’t the Jedi just acting as the enforcer arm of the imperialist republic?
Then we have a Jedi murdering women and children. Yoda knows about this. A senator knows about this. What happens to this mass murderer? Absolutely nothing whatsoever. While he is threatened with banishment form the order for disobeying a direct order on the field of battle, for mass murder absolutely nothing happens. No prison sentence, no banishment, nothing. The state and the order know that its Jedi are doing this sort of thing and nothing happens. So much for the Jedi being the keepers of peace and justice. They willingly accept murderous thugs into the order. So much for the senate/republic being the good guys. If you murder women and children on a non-republic world they no only do nothing, they actually allow you to continue to act as police officer.
But he was crying about it later, so that make it okay I guess.
Then we have to Jedi walk into a bar, hit someone with a lightsaber, and when the crowd gathers round the senior officer says “Jedi business’ and everyone shrinks back. This strongly implies their they were frightened, or they know there is absolutely nothing you can do about Jedi actions.
The impression I get is that the Jedi are brownshirts for the ‘democratic’ imperialism of the republic. I’m sure this wasn’t Lucas’s intent, but that really is the way they come across. Allowing a mass murderer to stay in the ranks of the Jedi means that the jedi have no moral right to tell anyone what constitutes just and legal behaviour, and the Senate/republic has no right to suggest that it is compassionate, just r taking the moral high ground. The movies no longer have goodies and baddies. Just two sides with legitimate greivances, on fighting a ‘War of Independance’.
