It grossly stretches the imagination to believe that a family of four, none of whom is even remotely qualified as a mariner, successfully operated and navigated a ship from Beirut, Lebanon, in the eastern end of the Mediterranean Sea, around Crete, Malta, and Sicily, through the Strait of Gibraltar, and across the Atlantic Ocean to the entrance of the Chesapeake Bay or to any other point on the East Coast of the USA.
At one point a Coast Guard petty officer refers to the "running lights" of the foreign cargo ship. "Running lights" is a landlubber's term. The correct expression is "navigation lights" or "nav lights".
It's absurd, unlawful, and grossly unsafe for any one or more of the agencies of the government of the USA to have refueled the ship in question and to have turned the family of three -- the mother and her two sons without the father -- loose -- alone -- without a qualified crew -- to operate and navigate the ship back to Beirut, Lebanon, in the Mediterranean Sea, or to anywhere else. Yet that's exactly what some combination of federal flunkies proposed to do. They even completed refueling the ship.
When Abby phones Gibbs to let him know that the father of the Lebanese family is a terrorist, you can clearly see the face of her cell phone and it shows the menu page, not a dial screen.
In the dialogue various characters repeatedly refer to the victim as an "officer". The vic is not an "officer"; that is, he's not a commissioned officer. Instead he's an enlisted petty officer. The single word "officer" standing alone implies a commissioned officer, not a petty officer. It's incorrect to refer to a petty officer as an "officer".
