First - is it not possible that the 80 year old white woman could be living in a Middle Eastern country? An assumption is made that if someone is Middle Eastern they must racially look a certain specific way and that's not always the case. Therefore racial norms are not specifically an indicator but a geographical one (ie., Middle East) could be, a religious one could be, and specific factors which are not constant such as how the person acts, what they are carrying, how they behave, and did the person pass all of the security check points. IF they did --- it may be enough based on geographic location, country of origin or religion to have them go through a second check, which would verify they are not on a terrorist or no-fly database. This could take hours to days to verify depending... I have no issue with that.
