4 year old banned from airlines.

Four year old Edward Allen was almost prevented from boarding a plane for a visit to his grandmother, last Dec. 21, because Continental Airlines had his name on a list - the Transportation Security Administration's "no-fly" list, established immediately after Sept. 11, 2001, which is supposed to prevent people who may have terrorist ties from boarding commercial flights.
Other names that have appeared on the no-fly list are those of Rep. John Lewis and Sen. Edward Kennedy.

Page 10 finds this story interesting for several reasons.
1) How did people with names like Lewis, Kennedy, and Allen get onto a list of people who may have terrorist ties? These are not the surnames you expect to find in the Baghdad phonebook.
2) A name like "John Lewis" is pretty common - how many people have been kept off airplanes because some guy in NY or somewhere made a deal in the Middle East once?
3) What good is this list, anyway? Supposed the real Edward Allen, friend of Osama, tried to board a plane, was turned away, and complained. Would he eventually be allowed to board, or is there somebody, somewhere, who can point to this particular guy and say "You're the one we intended to ban from flying, not all those other guys!"?
4) Is the name ever taken off if the actual person with terrorist ties is arrested and sent to prison? Or do people still get turned away for having the wrong name, even though Mr. Right Name is gone?
