Nationality and diversity in choosing judges

I do believe that one of Bradley's judges resigned after the fight. In one round Pac landed punches 2 to 1 and the judges still gave it to Bradley. Provodnikov beat the Hell out of Bradley, was cheated out of one of the knock downs by Bradley's referee, then left Bradley on the canvas at the end of the fight. Bradley was damaged badley, could not talk right for two months, was dizzy, etc. As far as Marquez? Marquez would land three punches and the commentators would say nothing, but when Bradley missed they would tell you that Bradley landed.
