I would define a 'robbery' as a situation where a fighter who clearly lost the fight won on the judges scorecards.
I wouldn't say this counts as a robbery because every party has admitted that the fight was very, very close. I personally scored it for Melendez but it's not a ludicrous argument that Henderson won, and there's actually a pretty convincing case for it. Look at everyone's scorecards on this forum, they're all over the place.
Rich Franklin - Holly Holm - Carlos Condit - Andrei Arlovski
