I had a briefcase at one point, but it was a kind of 1980s New Wave briefcase. It was made of some kind of cardboard and it had metal hinges. It was kind of faux industrial looking, and I used to carry my books in it rather than a backpack. I didn't want to have normal student accoutrements.
It would be wrong to say that the city of Berlin is not regulated. What I think is more interesting is to what extent a city creates a sort of safe haven for its users, so that people feel confident that the city works on their behalf.
