The judge ie wrong in his ruling
I most strongly agree with the judge.
Only that which is discernable to the unaided human eye from a point accessible to the public outside the property should not require a warrant. And further ANYONE operating drones or aircraft below 500 feet altitude above private property is invading privacy.If aerial device is camera equipped tha view should match that of unaided 20/20 human vision.
I would never find anyone liable for destroying an intruding drone.
Technology CAN be limited. Note that laser pointer abuse is much reduced from when first available.
