Christiania is a autonomous enclave situated in a former military base in Copenhagen.
At its entrance there is a sign which is presumably intended for tourists...

The English version says "No photos - Buying and selling hash is still illegal", but the German version says "Please do not photograph the purchase and sale of hash remains illegal [sic]". The German version does not have the same meaning when translated against the English version. In fact the semantics of both versions invite questions.
So what is actually illegal?
- Taking photos?
- Buying and selling hash?
- Taking photos of buying and selling hash?
- Or all three?
If the latter, is it OK to take photos of other aspects of Christiania, like the architecture? Which of these meanings should the well-intended tourist adhere to? More importantly, who would arrest the tourist if they photographed an illegal subject in Christiania?
Secondarily, there is an advisory against running, "Don't run - it causes panic" and in German "Please do not run, it generates panic". But there's no such rule against running in Copenhagen (that I'm aware of). What is special about Christiania that makes this rule necessary to the extent that tourists require a law/advisory?
Note: Since I took the photo outside of the "border" to Christiania, I assume that I was not in breach, but would welcome any well informed confirmation of this.
Note: Comments resolved the intent of the German text to mean "Please do not photograph - buying and selling hash remains illegal" (missing dash)
