The legal term is "reasonable expectation of privacy" (per the supreme court) and sadly it is not a boolean, it is an 'it depends' answer. > filming private property that isn't yours from a public space isn't legal if that's your intent. This is exactly what the "Streissand effect" case was about. Its the legal reasoning behind how the paparazzi operate (How else would we have pictures of what Taylor Swift did at her private 4th of July party?). It is absolutely protected speech to film/photograph private property from a publicly accessible location (if it is a privately owned public location that you are filming FROM, like a mall, then you must stop when asked. You are not required to destroy the material however). Edit: This is all in reference to US law.
