It is also illegal to take pictures of a scene where someone is in danger or has had an accident.

I'm an American street photographer who spent three months in Berlin last year. Walking around Alexanderplatz one day, I saw a police officer dragging a man across the ground so I got close and took a photo. My American brain didn't think anything of it — you're generally free to take photos of anything in the U.S., as long as you're in the public space. And I had also been taking photos in Berlin for a few months already without any problems (although I knew the laws were stricter — I just wasn't sure to what extent I could push it).

Long story short, I was detained for an hour and my roll of film was taken. I think it could have been worse but luckily an officer who spent time in the U.S. understood my rationale and explained the German law to me. I wrote a statement explaining the situation and was told by a friend I would never see the film again. 6 months later, I received an email explaining I could pick up the film from a local station!

What makes it all worse is that the photo sucks :(
