I think it has been addressed by the courts. A lot of it boils down to what expectation of privacy do you have in any particular place? Ubiquitous surveillance moves the bar and so there are places where an individual may have had an expectation of privacy 25 years ago and today that expectation is reduced.
In this particular case, Houston’s shenanigans were visible from a nearby public road. There’s no way he should have expected privacy.
