My hubby said that he also talked to someone he knows in the AZ Game and Fish, and the guy told him that as long as you do not have a sign posted on your property that says: No Trespassing No Hunting" that they can do it. (Something about the law). Gary said that the law for archery differs from the gun law.
Well, the way I see it, he discharged a weapon on my property and then trespassed to steal something on my property. By that logic I believe I have to right to defend myself, my family and my property.

Actually, based on what the 2nd person at AZ Game & Fish told us, it's not quite as simple as what your husband was told. There's no hunting within a certain proximity of occupied structures and he was WAY too close to our houses, well within that proximity limit. There's also a requirement according to the law, which I have a copy of, that hunters get permission from the property owners to trespass for hunting with projectile weapons. "Without the resident's permission, you may not discharge a firearm within 1/4 mile of an occupied residence while taking wildlife." There's also laws regarding shooting across roads, and shooting from a vehicle. He did all three. And unfortunately for him, despite his claims that he shot the deer down the road and it ran onto our property, we have video surveillance on our property that shows him breaking all three of those laws.
