Coincidence or Conspiracy?

Have you noticed that pairs of Middle Eastern men have been popping up in the news this August, only a few weeks away from the 6th anniversary of 9/11?

Case #1

Suspicious behavior on the Washington State Ferry system.
(Identities unknown)

Aug 20 the FBI asks for the public to help identify the above two men.
From Seattle King 5 News:

The FBI says the men were seen on more then one ferry and more than one run over the past several weeks. They were also taking photos of parts of the boat, which the agents won't reveal, but that apparently aroused the suspicions of passengers and crew alike.

Case #2

Indicted for carrying explosives in South Carolina.
(Ahmed Mohamed & Youssef Megahed)

As reported by the AP

TAMPA, Florida - Two Egyptian students at a south Florida university were indicted Friday on charges of carrying explosive materials across states lines and one was accused of teaching the other how to use them for violent reasons.

Ahmed Abdellatif Sherif Mohamed, 24, an engineering graduate student and teaching assistant at the Tampa-based University of South Florida, faces terrorism-related charges for teaching and demonstrating how to use the explosives.

He and Youssef Samir Megahed, 21, an engineering student, were stopped for speeding Aug. 4 in Goose Creek, South Carolina, where they have been held on state charges. A federal grand jury in Tampa handed up the indictment.

Observations:

Both these incidents have similarities other than pairs of middle eastern men being involved. Both occurred near Naval installations and both installations have nuclear submarines berthed.

In the first case, of the men on the ferry, one of largest ferry routes is the Seattle to Bremerton run. Bremerton is the home of the Puget Sound Naval Shipyard (PSNS) where nuclear powered ships are serviced including submarines.

The second case occurred in Goose Creek SC outside of the Charleston Naval Weapons Station. The Naval Weapons Station also has a command that trains nuclear reactor operators on a former Ballistic Missile submarine.

I wouldn't want to speculate too much but this coincidence is a little disturbing to this former bubblehead. I wonder if the FBI is checking the records of foreign trained ferry captains and harbor pilots?
