Since we frequently hear stories about the supposed inept security staff at US airports, I wanted to let you know that, in fact, they do occasionally stop bad guys. On Friday, security screeners at John Wayne Airport in Orange County, California (SNA), arrested a man who tried to carry a gun and a 6-inch knife on board a flight bound for Washington, DC. The man did not have a criminal background, nor was he on any of the terrorist lists. In any case, the screeners did manage to spot the proverbial needle in the haystack. For all the grief the screeners get, think about what a miserable, difficult job it would be to look at x-rays of hundreds of bags, hour after hour, knowing that there is nothing abnormal about virtually all of them. Blech.
