I'm not for shooting trespassers, even armed ones unless I feel they're a threat. Near as I can tell - trespassing isn't at play here.
It's generally different based upon where you grew up. Guys out west seem to think it's okay to be on land, so long as it wasn't posted. Where I am - posting or not, unless you own it or have permission from the guy who does - you don't go on it. Ever. Posting means ZERO. I don't hang a sign on my car saying "don't steal it" - you just know - you don't steal cars. Same with land use around here.
