With his arms folded tightly around his chest, Apple's lead attorney Orin Snyder appeared to seethe as he began to question Thomas Turvey.

Turvey, Google's director of strategic partnerships, was in federal court in Manhattan as a government witness. He was there to add credibility to the DOJ's allegation that Apple, one of Google's biggest rivals, had conspired with five of the nation's top six book publishers to limit Amazon's ability to discount books and remove a key competitive advantage. The high-profile case is likely to help remake the ebook sector and determine who the frontrunners will be.

But from the moment that Turvey sat down in the witness chair, Snyder began to attack his story. Turvey told the court that in early 2010, representatives of the five accused publishers, all of which have settled with the government, told him directly that they were switching to the agency model because contracts they entered into with Apple required it. But under oath, Turvey acknowledged that his lawyer helped him draft the statement that he filed with the court and that he was unsure whether he or his lawyer wrote important passages in the statement.

Things went downhill from there. Under Snyder's questioning, Turvey acknowledged that he couldn't remember a single name of any of the publishing executives who had told him Apple was the reason the publishers were switching their business model. He conceded that the publisher's move to the agency system was important to Google's own business, but Turvey couldn't remember any details about the conversations with publishers or where they had occurred. By the end of the interview Turvey had gone from saying the publishers had told him directly, to saying they had merely told people on his team, to finally saying the publishers had "likely" told someone on his team.

It was a topsy Turvey moment for the increasingly unsure Google exec.

The trial between the DOJ and Apple began on Monday and things were largely going the government's way, but today, DOJ lawyers appeared to goof. Much of what they were trying to prove with Turvey's testimony, DOJ lawyers had already presented to the court, with Apple's own emails, testimony from the likes of Penguin Books CEO David Shanks, and three separate Amazon executives.

By introducing Turvey, the government allowed Apple to cast doubt on their case. It appeared that the government was letting Google, which was never a significant player in ebooks, try to pile on a rival.

Outside the court, Turvey appeared sullen and declined to comment. Snyder (in the photo above) and the Apple team also didn't wish to talk, but were all smiles as they exited. It was obvious who walked out feeling victorious.
