No AZ law says you can use deadly force when you perceive a threat. In my case, if the cross all my gates, and get past my dogs, I believe they are a threat.I CC every day and have always thought the morals and ethics of deadly force was the most important topic when one carries. Even more important than going to the range is have a good idea of when to use deadly force. Morally for me it is to protect myself and others from physical harm if that harm might cause death to some severe injury. If AZ law really says that a landowner could literally set up a shooting range on his property near the border with a ice cold Kool-Aid stand and pick them off when they stop for a drink. I think shooting people that cross your lawn and causing no physical theat makes you a murder. AZ might have lower standards...
