The drone stuff has come up a few times due to them being shot down and their ability to view from the air which is not really owned.
What happens if someone hooks a camera in a tree and just points it at their neighbor’s pool… well… who the heck knows.
I’m just mostly saying that if you can stand on the sidewalk or in the street and basically get almost the same shots, it’s generally a public space. All of this is from USA POV. It seems like other similarly developed countries have a heck of a lot more privacy laws and considerations than we do.
