The fellow in question has travelled to Khartoum and Damascus. The entry stamps on his passport prove that. Obviously, if he was indeed a spy, he would have tried for a clean passport. The trouble is, that those entry stamps have already been noted by US Homeland Security. The information no doubt would have been posted to their counterparts in Tel Aviv. So, its not that easy, neither can we believe the story as its fed to us. The point is, when in doubt, you either lock up a suspect, or if you feel that he is not that much of a threat, you stamp a denied entry on his passport and send him home. The problem is that the fellow in question will now be on a special list both in the US and her allies. All his friends and acquaintances will no doubt be included, probably even the Vietnamese lady at the local dry cleaners and his speech therapist. Cheers, from cold Swiss Alps.
