The U.S. Terrorist Watch List appears to be growing in some kind of automated fashion. Given the current size, it seems to have run into Bonferroni's Principle. In fact, the example of Bonferroni's Principle in those lecture slides seems like it describes exactly what seems to have happened with the watch list.

If someone were to find out (from a friend of a friend of a friend, or by data mining) which people are getting added to the list, it would suggest a method of civil disobedience: organizing a lot of people to get themselves automatically added to the list. But the list seems to be imploding (in usefulness) just fine all by itself.
