Got a question for you.....
As the operator of those ports do you hold ship manifests( meaning knowing what everything a ship is holding) Ship scheduleds and their crews? If Im not mistaken the answer is yes.
Now Do you want some 3rd level muslim flunky with a heart for Jihaad to have that info?
Yes or No?
That would be the local port authority and various federal agencies. They don't employee 3rd level muslim flunkies.
