I understand that if I want to take a picture of an area for commercial use, I am beholden to copyright laws.
As per 17 US 120,
The copyright in an architectural work that has been constructed does not include the right to prevent the making, distributing, or public display of pictures, paintings, photographs, or other pictorial representations of the work, if the building in which the work is embodied is located in or ordinarily visible from a public place.
The inside of a mall is an open space, but it is privately owned. Is it considered a "public place" by this definition?
