Something Foul in the state of Egypt

So, a guy is busted in Egypt getting off a plane from JFK with guns, ammo and other weapons in his checked bags.

Aren't ALL bags checked and x-rayed by the TSA before they are put ON a plane? Why the Hell weren't these things caught on this side before the plane took off? Or, where they declared and the proper customs paperwork with ATF and Customs filed and Egypt didn't know?

Sorry but with the expert eye of the TSA watching out for our safety (is that for the children?) how the hell could this have happened? I guess since the guy hasn't had penis enhancement he wasn't a suspect.
