How does he get shot? It is internet controlled, right? Why is he trespassing on private land?
It wasn’t private land it was power company right of way, and leaving a deadly device out is illegal. Next thing to fool rigging a shotgun to go off when someone opens a door. All of which has worked out badly for the fools that did it.
Yeah, trespass is an issue. From the setup, I don’t think accidental discharge would be a problem either. Even if it goes off, it’s not going to hit anyone unless they are trespassing on his property. In which case, the question becomes why the homeowner has an obligation to ensure the safety of those who enter the property without his permission.
