and a food-production facility too? subject to USDA inspections and a whole set of regulations, being that what comes out of it has direct impact on public health?
Certainly there should be provisions to protect the privacy of the people living there, as there should be ways to ensure that also the public good is served and protected.
Your farm is not a house, it is a farm. A house that might happen to sit on the same land parcel is of absolutely no interest to anyone. Your private life simply is not that interesting.
Your commercial operations, which occur outside the house, are an entirely different matter.
Instead, you're so deathly afraid of it that you think you need to apply something even stronger than the extraordinary privacy protections afforded to homes to your place of employment by criminally punishing your employees for gathering evidence of your wrongdoing.
That is an insane leap unknown to the American legal tradition. You simply do not have a legitimate interest in preventing lawfully-present individuals from reporting your illegal activities.
