Another option is to introduce a HIGHER value target who just happens to be there... a Jedi who survived the purges would be a good one. So, when the Empire shows up and everyone starts running, they're just one of several targets. Sure, they Empire wants the people (not even really Rebels, at this point) who destroyed the Star Destroyer, but there's also Kram Akmr, the Jedi General of the Battle of Quadloo, who managed, not to EVADE his clone troopers, but SUBVERT them into not following order 66.
