premise: Sir Ian Blair, the Metropolitan Police Commissioner, said, last night, that his officers were "playing out of their socks", but admitted that they were "racing against time" to track down the bombers.
hypothesis: Sir Ian Blair worships the Dark Lord Sauron.
reason: From the context, we do not know whether or not Sir Ian Blair worships the Dark Lord Sauron, so the statement is neither definitely correct nor definitely incorrect.
