i would choose D. the inspector is trying to prove that he always knows when someone is trying to cheat him... but if someone who is trying to cheat him (by wittingly carrying contraband) passes unstopped, then his accuracy in detecting intent isn't perfect.

Another vote for E folks. It alone exposes the logical flaw inherent in the inspectors argument. The argument - inspector can always TELL whoever is carrying contraband and TRYING to deceive him. However how about if someone is carrying contraband unwittingly. In this case there's no deliberate attempt to deceive and hence the inspector wouldn't sense it.

Fact: Guy points hand at some one and they turn up being bad guys, carrying contraband goods.
Conclusion: Guy is good in finding people who deceive.

The missing piece is, "What about people whom does not point hand at? Are they always good guys?"
If the answer is "Yes", then it makes sense to say he is good in finding cheaters.

This flaw is pointed in D.

(I am a little skeptical about the use of "could" in all four choices except C. Using "could" does not make a strong objection. It would have been better if it were a past-tense-fact)

Argument - the inspector, based on his 10 years experience, has always been able to catch those carrying contraband and trying to deceive him. One of the central pieces of his argument relies on the assumption that those carrying contraband knowingly try to deceive him and he catches them.

E exposes a possiblity that some people may unknowingly carry contraband and hence there would be no question of them trying to deceive. This exposes a LOGICAL FLAW in the inspector's argument that he can always tell those carrying contraband.
