Heard on the radio this morning while driving to work. Story about a woman who discovered that her 11-month old son was a terrorist. How could this be? A ticket agent at an airline prevented the child from boarding a flight. That's how. It seems that the given name of the child was found on the list of people to be prevented from boarding flights. It would seem that, in the context of merging topics in a topic map, it's dangerous to rely on names for things as a valid criteria.
