The CIA has been earning rave reviews for the pitch-perfect comedy of its newly created Twitter account.

But while facetious tweets like "No, we don't know where Tupac is" or "We can neither confirm nor deny that this is our first tweet" have lent a little levity to an intelligence community buried by Edward Snowden's airing of its spy-program laundry, the comedy has not dissuaded journalists from fact-checking at least one of the account's claims.

In a lengthy article Friday, Washington Post journalist Barton Gellman attempted to answer some questions that have surfaced since he reported last week on a new Snowden leak. Buried deep in the report is a two-paragraph gem that says the CIA's Twitter, while funny, is also propagating misinformation.

The CIA opened a Twitter account last month and has used cheeky humor to win a large following in a short time. On Monday, the account sent out this announcement: "No, we don't know your password, so we can't send it to you." It went viral, with more than 12,000 retweets.

As it happens, the [National Security Agency] files we examined included 1,152 "minimized U.S. passwords," meaning passwords to American e-mail and chat accounts intercepted from U.S. data links. Don't expect tech support from Langley, but the CIA does have access to that raw traffic.

Those numbers come from a batch of 160,000 intercepted communications provided by Snowden, a tiny sample of the Internet data the NSA routinely collects. U.S. communications that are incidentally collected during surveillance of a foreign target are required to be "minimized," meaning there are limits to how they can be searched. But such searches are not forbidden, and, Gellman notes, agencies can distribute U.S. identities in reports to one another.

Gellman's big NSA exposé last week claimed that the vast majority of Internet accounts monitored by U.S. intelligence agencies do not belong to overseas targets, but instead to ordinary Internet users who communicate directly with those targets.

The implications of Gellman's story are profound and serious, and partially refute some findings in a report from the president's independent privacy-watchdog panel, which declared the NSA's foreign surveillance techniques legal and effective.

The CIA Twitter account's may be attempting to leverage levity for flexibility with the facts, but that's unlikely to quell the horde of anti-surveillance activists who claim the intelligence community has persistently been misleading and dishonest about the true magnitude of its spy programs.
