Here is a brief excerpt from an entry at my all-time favourite blog Lizas Welt. Liza informs us that the Bundesgerichtshof (BGH), the highest German court, ruled that the usage of the slogan "Ruhm und Ehre der Waffen-SS" (Glory and Honour to the Waffen-SS) is legal, whereas a provincial German court fined a student 2,400 Euro for using the book cover for a flyer. They took issue with the "Hitlergruß" the Pals are performing. Not with the fact that they do it, mind you, but with the fact that somebody used the photo.
Both trials were based on § 86a StGB (the German penal law), which covers the usage of symbols that violate the constitution.
