Presumably she did some things that were illegal even by Old Republic standards. Streaking is still a crime no matter who’s running the galaxy. 😛
Thanks for your answer but im looking for a more provable explanation. I don’t think the Rebels would mind their own troops resisting arrest by the empire as it would only help themselves. To be more clear, im thinking of cutting this outrage over her being a criminal in my fanedit as I see no reason for them to think this way.
