even though the scenario is highly artificial and irrelevant...
Obviously you go for the guy coming into the airport. Not because he is the greater threat, but because you know where he is. He's contained. You don't know where the illegal waiting to cross the border is, so you have no chance of stopping him at all.
Can we get back to reality now instead of posting silly meaningless quizzes?
U.S. border security scrutinized after TB patient slips in
A senior House member wants to know how a dangerously infected man managed to get through U.S. Customs and Border Protection even though his passport had been flagged in their computer system.
Andrew Speaker, an Atlanta, Georgia, personal-injury lawyer infected with extremely drug-resistant tuberculosis, flew from Europe into Canada to avoid a no-fly order in the United States. His passport was checked at the U.S.-Canada border, a Homeland Security official told CNN.
An alert that Speaker should be detained and isolated, and public health officials should be contacted, showed up on the Customs and Border Protection computer system, but he was allowed to cross into the United States at Champlain, New York, anyway, the official said.
Speaker was at the border crossing for less than two minutes.
