My personal interpretation depends on what the definition of "property" is.
If property includes all your belongings -- cars, money, credit cards, cell phone, GUNS, AMMO, etc. -- then you are not allowed to use deadly force. If the intention of the criminal is to simply take your stuff and leave you alone, then you are not justified in using deadly force. This is particularly true if the thief is running away from you with your stuff.
If, however, property means your yard or home, then YES! You can stop someone from entering your property if you believe their intentions are to harm you or your family/friends there. The person coming onto your property can stand around and refuse to leave, and you can't use force. Call 911. But, if you are in your house and they are trying to break in, you are free to assume they are going to assault and injure you. Self defense is legal.
Best plan is to call 911 and LEAVE THE LINE OPEN. Let the dispatcher and the 911 system record what's going on. They'll record you warning the person to stop, to leave, and to come no closer, or else you'll shoot them. There's a clear recording of the events to show you did everything right.
Also, make sure his fingerprints are on the large kitchen knife the Cops find next to the body.
