I don't know if I recall the Iraqi in the house is just trying to calm the man with the gun down because hes probably confused and doesn't know who Beckham is. I think the stall operator dropped him off at that house just because he wanted to get him out of his car

i think they tried to give the Iraqis a more human/individual side when they had wild man bomb-boy force the dvd guy to take him to what he thought was the little kid's house. When he barged in gun in hand all crazy eyed looking for a kid who wasn't there, it was the Iraqi (who I believe was a college professor) who played the role of civilized person to the wild gun-toting American heathen.
