Consider: What if a thief wasn't P*d but rather the neighbors dog? What if the farmers four year-old child died as a result of eating the said P*d crop while playing outside?
Neighbor's dog: partly accidental, partly the fault of the neighbor for letting their dog trespass, partly the farmer's fault for not preventing the trespass.
For the child: mainly the farmer's fault for not preventing it.
I thought we were talking about law?
I thought we were talking about ethics & responsibility.
The law is clear that your property is the public's business. Ownership gives you only certain rights. The right to file charges against tresspassers is one of them. The right to kill in offense is not.
It is also clear that the law is not always right.
Well, assuming that the poison is not at all pesticide related, and was genuinely intended as a measure to get back at the thief then certainly the farmer is guilty of manslaughter if not murder.
Disagree. One has the right to protect themselves and their property. It was the thief's choice (though not his right) to steal, and he's responsible for his own actions. The farmer did not induce the theif to steal, therefore claims no responsibility.
As some people (especially in the US) seem to like to forget, it is possible to over-react to a threat to your property, and there are measures of retribution which are worse than the crime that was committed in the first place.
Agreed.
Along that vein, I once saw a show about mandatory classes on the moral and legal issues of lethal force on the Outdoor Life Network (or something like that, I was channel surfing at the time) and they had a clip from some classroom or other which displayed some Forman for a construction sight or the like and he was arguing with the instructor over whether or not it'd be right of him to shoot some kids that had been stealing tools or materials from his site at night. The instructor informed him that you can't just go around shooting people, and that a concealed weapon is only for when your own life is in immediate danger. The foreman of course just crossed his arms and huffed with a glum look on his face that seemed to imply he'd been disillusioned with the idea of owning a gun for his "protection" and was beginning to ponder the pussification of the United States. I think that bringing up this example might lend a little more real world perspective to this hypothetical situation;
They're just kids and have no reasonable expectation of being shot. In such a case, the punishment would not fit the crime. With the farmer and thief, it's a different situation.
I just went back and read the OP, and it does imply the farmer suspected the crops would be stolen, and that it was done to punish a would-be thief. In this case, the punishment does not fit the crime as well, and I would hold the farmer accountable. I'll leave the previous parts of my post intact as they made valid points.
If the farmer had done it for another reason. ie., to destroy some crops, then he would not be accountable, as he has the right to do so. It comes down to intent.
