White hats have had to fly under the radar for many, many years.

How long ago was the Plan devised?

I believe there are many "FBI anons".

Sitting here watching movie National Treasure.

FBI agent Sadusky is wearing a U.S. Marine Corps necktie.

And a Freemason ring.

"Much of Sadusky’s distinctive plain clothes uniform was suggested by Keitel himself, eager to reflect a more individual look than the cliché FBI image of dour suits and plain cotton shirts. Hoping to get across semblance of Sadusky’s past, he also put forward the regimental necktie idea. This helps explain why Sadusky is so impressed with Gates and his naval diving experience from the outset. By employing this uncustomary look for a federal agent, Keitel has ensured his character stands out from the herd. Though not from a vanity perspective; we get to know and like Sadusky considerably more than other similar characters from similar movies. By costume alone we understand him and his sympathies that bit better."
