Yeah, so this makes more sense. Even if I accept this statistic about Iowans, which I am fairly dubious of, your position still doesn't make sense. You would be saying that in situations of crimes of passion, gas station robberies, etc that it would be more likely for an Iowan to commit a murder than someone from Saudi Arabia (again, still dubious claim but I will grant it), this doesn't say anything about terrorist acts particularly related to air travel.
