Bad call. Make immediate protest to RM. Too late now.
I ran into the same type of idiot that Fishinfool did, and demanded the target be immediately pulled and scored by a higher official.
Watch out for yourself, and speak up right then.
By the way, changing the shooting order just as someone is standing there to shoot is one of the dirty tricks some ROs use to help out their buddies, and they need to be identified and "retrained."
