traps are a felony. There is a famous case about a guy whose bldg kept being broken into so he rigged a shotgun pointed at doorway to fire once door opened and person came in. Bldg owner convicted. Someone else rigged a bear trap to catch a ,online breaking in. He caught the person breaking in but he went to jail.
There is a good chance this guy will be charged as well even though he used a non lethal weapon to batter the guy in this heavily democratic area
A political sign is not a trap, or is it? It will be decided By a 5 to 4 SCOTUS Ruling Im sure.
Not the same has putting a deterrent on a sign on your property. I'm guessing electric fences aren't just for farms, but folks put them around their gardens to keep the deer out, etc.
“Oh my! I electrified the sign because the deer kept nibbling on it - I never imagined a person coming onto my yard and messing with my sign!!”
