Germany outlawed something related to suicide (or something that led to suicides), but it was not written or visual media, nor was it a manufactured item.
Was a specific activity outlawed?
Was disseminating information about a specific belief outlawed?
My summary: German adults who were trying to hurt other people did a thing that was later outlawed because it resulted in human deaths. Most reasonable people would consider the thing they did to be stupid. The deaths occurred in multiple different ways. They had something to do with suicide, but the people doing the stupid things were not trying or intending to commit suicide. The outlawed activity was kind of in the area of a challenge, dare or bet.
Were the people doing the stupid thing the ones who died?
Did the people doing the stupid thing intend to kill the people they were trying to hurt?
Were the people doing the stupid thing trying to hurt other people physically?
Were they trying to hurt other people mentally/emotionally/psychologically?
Were the people who died trying to die? Were they trying to be hurt?
Were the people who did the stupid thing police officers?
Were the people who did the stupid thing all in the same profession?
