No, the poster was asserting that the nationality of the suspects was being witheld. It was not.
Oh, one was a naturalized citizen. The others were arrested outside the United States, therefore their status is irrelevant at this point.
The flaw, as some have pointed out, is that our naturalization cannot catch terrorists with the low numbers being screened now. They will never catch terrorists if they have to process 12 million.
I see. For some reason the threadmeister edited out that relevant information [both the names and nationalities of those arrested] from the original AP article and posted an unecessarily excepted version, so I can see where some posters got the (mistaken) impression that the info was being withheld.
