No search warrant, no problem! Just use a drone to illegally search the property!
There is no warrant required to fly a helicopter over anybody’s land, and there’s not much difference between that or using a drone. The use of drones just doesn’t freak me out, all by itself. I don’t feel spied on when helicopters overfly my house... Having drones up there doing a similar job more efficiently seems like a good thing, as a taxpayer.
But I also don’t pull a gun on everybody that comes to my house. Maybe this farmer could be a little less trigger-happy and more reasonable and he wouldn’t piss off his neighbors so much. Being a good neighbor is part of living in —and preserving— a free country.
