Earlier quoted context omitted.
It was a series of videos taken in public where a guy would just point the camera at people doing mundane things. The subjects would often question why he was filming them and the response was always simply "oh, I'm just making a video". Occasionally the guy would elaborate further and it seemed the point was that people are captured and recorded on CCTV and other surveillance methods all the time, so why would they…
>so why would they care about his camera? I mean it seems pretty obvious. Because a private person could potentially do anything from stalking you, to using your image in some political campaign or advertisement or whatever else. Potentially much worse and intrusive than being filmed by a parking lot camera. Here in Germany it even is illegal unless consent is given.
You can't legally use someone's image in an advertisement without their consent. But that's different than having the right to film in public. If I'm filming and you walk in front of my camera, you don't have the right to force me to stop filming. You don't own public space.
