'Unusually High Number' on No-Fly List Trying to Board Planes

This report from the UK's Mirror is very troubling:

Anti-terror officials said the past week had seen an "unusually high" number of people on their no-fly list trying to board US-bound planes.

Why would terrorists try to push people on the no-fly list through? Diversion. While security is busy investigating a no-fly list attempt to board, others who aren't on the list can be sneaking through the checkpoint with IED components.

This is how FAA Red Teams often seek to distract screeners when testing airport security. They send someone through with a fairly easily detected threat, thereby causing a ruckus, while another tries to sneak prohibited items past the distracted screeners.

This is a bad sign.
