You sound like the stupid politicians in America. We don't want to offend any one by checking people who fit the description of the bombers (because they are of a certain religion and ethnic group) so we will check all the least likely suspects. Yes it is true that the 90 year old white American grandma may be taking a bomb on the plane and I have no objection to frisking her. But I have a real bias against people who complain that I am a bigot for saying that the terrorist sure seem to have a lot of identifiable features in common. If those features are blond females then I have no problem being stopped more often than a dark haired male.
