The facts, they are a changin'

The national intelligence office statement said the air samples were collected Wednesday, and analysis found debris that would be consistent with a nuclear test "in the vicinity of Punggye" on Monday.

"Additional analysis is ongoing and will be completed in a few days," the statement said.

The South Korean Defense Ministry told CNN that the United States has informed it that radioactivity has been detected.

The report is in contrast to information provided to CNN earlier Friday from two U.S. government officials with access to classified information. Those officials said that an initial air sampling over North Korea showed no indication of radioactive debris. |CNN|

I don't know what's going on here, but 'debris consistent with a nuclear test' is consistent with 'no indication of radioactive debris', so it's possible that CNN is getting spun.

...it helps to read the whole article. Still, I'd like to know who CNNs original sources were. Are we talking about idiots who didn't know what was up, or are we talking about insiders who believe that the national intelligence office has cooked the data? I lean toward the former, on the theory that my government would never lie about these sorts of things.
