I conquer with Denz: they have commited crimes such as kidnapping, endangering civilians, terroristic actions, threatening and using violence against the government (both of the planet as the Republic), damaged official infrastructure, etc.
They should get a fair trial, even if called for I would stay behind to make sure that they don't get mistreated during the trial. Perhaps I can get a droid over that knows law (sorry, I'm reading Sacrifice and Jacen Solo is using such a droid).
In defence of us asking to speak justice over them: they could have asked us, commed us or when entering through the bloody roof not drawn weapons and kidnapped the administrator but simply asked Jedi protection and than tell us what was going on.
Desperate times, desperate measures: I agree but there were other ways with no violence that they could have used.
