My two cents......
the landowner had and excercised his rights. But tells me what kind of man that he is on the inside. Not letting someone trespass for whatever reason, be they noble or just vindictive and self serving is one thing. I would have at least put the animals down. Ended their suffering. Has nothing to do with what nature dictates or what goes on without "man" seeing it. Has everything to do with compassion.
Whomever this land owner is?? Better hope that if he ever had an attack of some kind and lay suffering in need of aid ...........that someone like me with the knowledge of his past activities was not the one in whose hands his life now lay. For in the words of wise old man........I wouldn't urinate in his mouth if his teeth were on fire!!!! Just my opine....
