(CNN) -- A whistle-blower who helped shed light on misconduct among the ranks of contractors working as guards for the U.S. Embassy in Afghanistan is back home in England sooner than he expected after he resigned in the fallout of the scandal. "It was just downright stupid," Terry Pearson says of guard misconduct in Afghanistan. Terry Pearson, who worked as an operations manager for contractor R.A. International at Camp Sullivan in Afghanistan, said he witnessed mistreatment among the guards employed by ArmorGroup North America, who were housed at the camp. "It was just downright stupid, some of the things they were doing," Pearson told CNN. "And insensitive."
