this is exactly about what is legal or not.
If I remember correctly in Germany there's a distinction about people being the focus of a photograph or people in the background. You can e.g. publish a picture of a public place without asking everybody on that place for their consent.
Another corner case would be filming police brutality. What if the police officers in question wouldn't like to be photographed being brutal!?
Local laws do apply.
