I'm not sure the two things go together, wasn't their statement in response to the UK police reporting that they had this lead, not what the German police said? Besides which, everything will be filtered through spokespeople even before the press get to report it, so it'd hardly be representative of how they're feeling right now. Don't get me wrong, they're cold fish, and some of their previous behaviour has been downright odd, but who knows how people react in this situation.
