The key issue you are overlooking is torts which occur. A former tort does not excuse a more severe subsequent tort.
By your own admission, a farmer has permission to shoot a boy who climbs into his field to collect his football. The force used by the farmer is grossly unreasonable, as is the use of a knife. There can be nothing other than severe injury with a knife.
If the boy was to attack the farmer with intent to kill, as a the theif might have attacked a house owner with intent to kill, you would have a right to defend yourself. But entering the house or the field is not enough to justify such excessive force by itself.
At what point did I say trespass on land should be subject to being shot?
Trespass in a building (with or possibly without the intention to burgle or with the intention to be a chav) and I have no problem with shooting / stabbing / beating the crap out of the person
The key point is INTENTION, a boy getting his ball has no intention of doing any harm, this scrote did.
Nitefly is right, and you purposefully missed off the key point of his argument.
He didn't say that you said it was ok for a farmer to shoot a boy in his field for no reason. The point is, by your own admission, the farmer
has the right to shoot the boy for being in his field.
You dont know "the scrote" had any intention of harming anyone. He might have entered the house looking for a purse or wallet for easy cash, or maybe he just wanted to rearrange the furniture. On the flip side, the boy in the farmers field will find his ball and might well think to himself "Oh wow, carrots, maybe i'll just take a few of those while i'm here". That is directly comparable to "the scrote" in the house thinking "oh wow, a wallet. yoink", and having it away.
They are, i'm afraid, one and the same. I believe the reason you can't see it is, and quite understandably, because you're not a farmer with a field. You are a person with a house, though, and it's a more tense and frightening situation than standing on the other side of the field... but that doesn't mean you can dish out death as punishment. The field is private property as the house is. The field is also the farmers livelihood, his entire life depends on it.
Is it still ok to shoot a boy getting a football in a field, knowing that maybe, just maybe, that boy want's to half-hinch some carrots on his way out?
You dont know what the lad wanted in the house. You can't just kill people, just in case.
