Nutzlose Sicherheit - Useless Security

In his post, Udo Vetter from the German LawBlog describes how the security installations on a certain German court (without exactly telling which one) can be so avoided so easily by anybody, that it's a shame. Simply by memorising a certain PIN you can march into the court through the cantine without passing any metal detector or anything.
As one commentator there said: "It's like using biometric passes for Germans to prevent attacks by Arabian terrorists."
