I mean a literal 5-year-old child, not some obscure threat.

According to BoingBoing the child’s name is the same as someone else on the list, but according to this interview with the head of TSA by Schneier, you should only get a hit if the name and date of birth match. He was considered such a threat his mother wasn’t allowed to console him/touch him during the process.

Which gives us three options:

  1. This child really is a national security threat. Having flown on many planes with out of control 5 year olds, this is my best bet.
  2. There is another five year old in the world with the same name and birthdate that is the real national security threat.
  3. The TSA messed up

I find this amusing, and sad.
