GIVE HOMELAND SECURITY SOME CREDIT for this one, assuming it pans out as reported:

A British national was arrested this morning on suspicion of being involved in a plot to smuggle surface-to-air missiles into the United States, ABCNEWS has learned. . . .

Sources said the man, possibly of Indian descent, thought he was dealing with terrorists in the United States who wanted to shoot down a passenger jet.

The man was arrested in Newark, N.J., as part of an international sting conducted by the FBI, British and Russian authorities. The sting began five months ago in Moscow.

Hmm. According to this BBC report, this was a pure sting, with no actual terrorists involved. If all is as reported, it can hardly be called entrapment. It should, of course, have the effect of making other people less willing to deal with terrorists, real or otherwise, under these circumstances, which is the point.
