Nobody yet mentioned where this happened -- Oklahoma, I believe.
I'm unfamiliar with the "castle laws", whether OK has one, how much leeway it gives the owner.
I'll reckon that in Texas, this would be a "no bill" -- cops and D.A. will do nothing to the homeowner. But up one state in OK ... not sure.
The homeowner definitely was a good shot to put down all three of them.
I doubt any jury down there would convict him of anything.
Of course, times are a-changin' and I could be wrong about that.
