I read that the German captain asked his team mates at half time to show respect to Brazil and not humiliate them any more, hence why they slowed down. Imho it could have been 10+-0.
Whatever respect they showed is entirely negated by allowing news of it to reach the media. Now it's even worse for Brazil than it already was, as what dignity they retained was handed to them. If you do something like that, the key point is not to broadcast it,
