They will have no control over security...and yes, when you make silly comparisons to airport security, you are being very dense.
Especially when you have an Arab company handling port operations?
Does anyone suppose a terrorist might choose to ship through a port where the operations are run by an Arab company?
Does anyone suppose one of those big boxes filled with nasties could possibibly slip though a 2% inspection? Iguess there would be only a 98% percent chance it would, not very good odds at stopping it I would think.
