So the way the news is describing it at this point is that it's basically a farm / ranch. A person drove up the driveway and wandered around a little bit. Homeowner came out of a building that looks like maybe the barn and asked the person 'who are you what are you doing here' The man walked away or fled and apparently entered a home. So the homeowner shot him in the back in the foyer. There's a bunch of facts we don't know yet, but assuming the shooter owned the whole compound, was it legal in wa to shoot the guy? Does it matter if the house was empty or maybe had wife and kids inside? At first they said he got shot on the porch, now they are saying he set foot in the house. Strictly form a legal prospective does it matter? "what if" the shooter is a close neighbor and not the homeowner?
