I believe one in the hunting party was owner of said property. "Police" are under NO legal obligation to answer a call regarding a problem with a hunter (as in: "armed" and possibly dangerous), and the nearest game warden could have been a few counties away. No...this situation only proves how quickly a seemingly innocuous situtation can turn to $hit in a matter of seconds. It did and we all, sadly, have something to learn from this.
Never let your guard down and never let an armed unknown have a tactical advantage over your position.
