According to a newspaper article, a customs inspector believed that he could always tell if people were trying to deceive him. He based this belief on the fact that, in ten years of experience, in cases where he suspected that a tourist was carrying contraband, he was always right. Careful inspections of the luggage and persons of the suspects always turned up the contraband goods.
Which of the following points up a logical flaw in the inspector's reasoning?
(A) The tourists who passed through the inspector's checkpoint could have known that they might be searched.
(B) Only a small percentage of the tourists passing through the inspector's checkpoint could be expected to be intentionally carrying contraband.
(C) Other customs inspectors at the same checkpoint caught tourists carrying contraband just as often as this inspector did.
(D) Some tourists whom the inspector decided not to search could have -knowingly carried contraband.
(E) Some tourists who passed through the checkpoint without being searched could have been carrying contraband unwittingly.

Correct answer: D
The inspector correctly identifies all those whom he suspects. That fact has been substantiated. However, there could be other contraband carriers whom the inspector does not suspect.
(A): Incorrect. Out of scope: whether someone knows they might be tested does not determine whether the customs inspector was perfect in his identification of contraband carriers.
(B): Incorrect. Irrelevant: the percentage of tourists carrying contraband does not bear on the accuracy of the custom inspector in identifying suspects.
(C): Incorrect. Irrelevant: the passage concerns only the account of this particular customs inspector.
(D): Correct. The customs inspector may have neglected to suspect some contraband carriers, indicating that he could not always tell when people were trying to deceive him.
(E): Incorrect. Out of scope: (E) concerns tourists who were not searched, i.e. who would not have been in the position to deceive the customs inspector.
