I'm not sure I see the coincidence in the first place, honestly.
On the one hand, you have technology that is designed to prevent people from smuggling bombs/bomb parts on to a plane by concealing those bombs/parts on their person.
On the other hand, you have bombs that were being transported as cargo, a result of their having been
mailed to another country.
Since the bombs were not smuggled aboard on the body of a person, the proposed bodily x-ray technology the TSA wants to employ would not have (and
could not have) prevented what transpired here.
As such, any argument (or "propaganda campaign," if you prefer) that these attempted bombings could have been prevented by the bodily x-ray technology would be easily refuted, as it would be patently and obviously false.
If you're reaching for conspiracy theories connected to this, I'd say it would be much more likely that this was in furtherance of the U.S. defending its decision to target Anwar al Awlaki for assassination, and to bolster their defense in the civil suit brought by al Awlaki. Given that the bombing plot is alleged to be the work of the AQAP ("Al Qaeda in the Arabian Peninsula") and al Awlaki is alleged to be a leader of the AQAP, that connection would make some sense to me as the basis of a conspiracy -- or (more likely IMO) as an act of mere opportunism, should it be the case that the bombs are real but the connection to AQAP is not.
I'm not at all suggesting that such a conspiracy is at work... just that it is a more plausible theory than the airport security/ x-ray one.
