Based on the lack of details onn which you arrive at your conclusions, and general attitide towrds those who question them, I'm not at all convinced the lion is a threat, and that the fears are not based more on TV movies than lion experience.
I will speculate a little myself since you seem to get upset when questioned on specifics and details on which you base your dramatic conclusions.
How do you know it "got at least 3 cats"? Did you see it snatch them up? You do know lots of things happen to free roaming cats in rural areas that don't even have lions, right?
You left deer entrails 500 ft from the house, and you are surprised that wild animals got into it? You know that is like puttomng out food for them, right? Do you really know that it was the lion that got into it? Not that it matters, because when you put food out for animals, they tend to come and eat it.
I am skeptical that it is stalking you. Based on what? A sighting at night with a flashlight? Watching you is natural for any wild animal that is wary of humans. If it was actually "stalking" you, what prevented it from being successful? Lion attacks are extremely rare on adult humans, but if he was really stalking you, he would probably have been succesful. I've been watched by a lion, and it gives you a creepy feeling, but it does not mean you are in danger. If he truly intends to attack, he is a far more skilled at catching predator you than you are at evading him.
I'm glad you saw fit to discuss it with the right officials. I can't imagine them telling you to shoot it, but then maybe they figured you were blowing off hot air, and the cat would never ever become enough of a "menace" to give you the opportunity. You'll proabbly continue to see occasional tracks, but sightings will probably be limited to glimpse every now and then, so I'm not overly concerned about you successfully poaching it.
I could be all wrong, but the impression you gave a lot of people is that you are looking for an excuse to poach a lion based on irrational fears. I truly hope the lion is not dangerous, but I'm not very convinced that it is.
