That would be the same USS Cole that got attacked by jihadis?
So lets see - an ex-USN sailor, knowing that a ship has previously been the target of a terror attack that killed 17 US sailors, deliberately passes information on the ship's future movements through a possible attack zone to a known jihadi sympathiser already under investigation. Actually, this traitorous fruitcake had better hope he gets locked up, because I really wouldn't want to be him if his shipmates ever catch him walking down the street!
I am amazed the FBI actually needs more - as a signalman he would have known all about security, as a serving sailor he would have understood the value of the information he passed, and his use of codewords for Usama Bin Liner just goes to show he knew he was doing wrong. What do you have to do to be labelled a spy or a traitor nowadays, do you actually have to pull the trigger itself?
