Yeah, the linked article is garbage. You have to follow one of the links to even find the most basic facts about the case from the headline (like what agency put up the cameras and why):
https://ij.org/case/tennessee-open-fields/:
> Officers from the Tennessee Wildlife Resources Agency (TWRA) routinely enter private land on a whim to search for potential hunting violations. They don’t have probable cause to believe a crime is being committed, and they don’t ask permission from either property owners or a court. Instead, they trespass, wander around as they please, and take photos and videos. They even install cameras so they can keep watching the properties 24 hours a day, seven days a week.
