Unfortunately, that's always going to be a problem with it unless someone gets rid of the droid entirely and finds some way of showing her attempting the assassination directly. :-/
Why the bugs are necessary in the first place, I don't know.
Red Letter Media pointed out as much in his review....basically stating "if a droid can get deadly centipedes into a room, why not just shoot her? KABLAMO! No more Amidala." =p
