Additional testimony and questioning in the DOJ e-book price-fixing trial against Apple has turned the nature of the case -- which has already become more into a inquiry of Amazon's misdeeds than of Apple's -- so far away from where the DOJ wanted it to go that even Apple's own lawyers sat up and took notice when Judge Denice Cote asked a key question during Friday's hearing. Cote, who in various pre-trial statements had made it crystal clear she believes the DOJ's original claims against Apple, injected doubt into a key part of the prosecution's case.
