I didn't watch it but please clarify for me; are you saying that English supporters booed and hissed the German team during their anthem?
If so it's a sad comment on the times. I would have halted the game, emptied the stadium and invited back in anyone who was prepared to show a sporting attitude.

Yes that is exactly what happened, it started to die down a bit once the game got underway, but you were certainty aware of the poor sportsmanship evident in the crowd for a lot of the game.
