The issue with retaliation, and the point those of us are trying to make with these "what-ifs, disabled vet" scenerios is that there is always two sides to the story.
There could be a ton of legitimate reasons why someone is trespassing. And we could play these what-ifs all day long. Does it make it right to trespass..... NO. Should they be held accountable/punished/fined......absolutely. But as an individual/landowner....it dont give us the right to play judge-jury-executioner, and levy the punishment.
ITs a case where two wrongs DONT make a right. And slashing someones ATV tires for vengeance/spite/punishment is NOT a wise thing to do.
Again, there are some legitimate reasons, and we can play what-ifs all day long. The trespasser is 100% in the wrong, and should be held accountable. But it still dont give you the right to slash tires.
