No, I expect that they, the FBI, and Homeland Security all know about this as do the Coast Guard.
I didn't know about this and I would wager that lots of members of the public aren't aware of this. I also think that it explains and legitimizes alot of strange things that have been happening since September 11th, but didn't previously make sense. That "connecting the dots" is why I read Free-Republic and enjoy the posts here.
