The Montana rancher quoted in the article seemed to have a reasonable justification for it. I can't say I fully agree with him or that I'd press charges for it but he doesn't sound like he has ill intent. People firing guns and scaring his kids, trespassing deep into his land, parking in his driveway etc. And local law enforcement stretched thin and unable to respond consistently. So his position is basically I'm going to do everything I can to keep these people away from my property. That's understandable.
