Shooting to save property?
I think this is a very gray area in terms of what people perceive as shooting to save property. During a robbery, for example, a bad guy points a gun at you or a knife and tells you to give him your wallet. You draw, shoot, and kill the bad guy. You had $6.00 in your wallet, credit cards, ID, and some family pictures, plus a shopping list for groceries needed for dinner that night. Did you just kill a person over the contents of your wallet, totalling no more than a few dollars? Many people would argue that is exactly what you have done. That would be wrong, however. You defended your life from a bad guy who threatened you with harm. At the point and time your well being is put in danger, the fact that the bad guy wants your wallet is no longer of consequence. The confrontation is now one of life and death, not for the contents of your wallet. The issue of the wallet is only salient in that it is what attracted the bad guy to you.
I realize a lot of folks would gladly turn over their wallet and chalk up the incident to experience, file a police report, and comfort themselves with the notion that they could not use violence to protect something like their wallet. This sort of reasoning is based on the concept that the bad guy is essentially negotiating with you for your wallet. "Your wallet or your life" type of negotiations. The obvious choice is to give the guy your wallet, only why would you believe you will still get to keep your life? If the guy is breaking the law by robbing you and threatening your life, then why would you believe he is negotiating in honest good faith and will simply leave after getting what he wants? Giving him the wallet does not assure you that the bad guy will leave without harming you.
In such robbery situations, it isn't about the property at all. It is all about my life and the lives immediately around me.
Change the scenario. You are standing next to your car and you have your wallet on the hood a couple feet from you. The contents of the wallet are the same. You hear footsteps, turn around, and just catch a glimpse of a guy running full speed who has snatched your wallet off the hood of the car. Do you shoot him? That is your call to make. In that case, I would chalk the incident up to experience. My life is obviously not in danger, no threat was ever made, and now both my wallet and the bad guy are quickly gained distance from me.
So, many of the situations where people are said to have been killed over X amount of goods really are not situations where people are killed over the goods, but over threat or risk to life.
All that is in public. What about in your home? You come home and find a burglar in your home. Would you shoot the burglar? In some states, this is allowed by law and in some it is not. What if you wake up in the middle of the night and find a burglar in your home?
My thoughts are that if somebody is in my home, an intruder, they are a direct risk to my safety. Rarely do they wear neon signs that stipulate the reasons for being in your home, such as "I AM HERE FOR THE TV ONLY." As one mother repeatedly proclaimed on a talk show discussion concerning her dead son who was one of several unarmed kids that invaded this guy's home as part of a gang initiation, "The penalty for trespassing is not death!" Sure enough, the penalty for trespassing is not death. However, the homeowner was 100% justified in his actions. He went as far as to identify himself, announce that he would shoot, and the boys advanced on his position, coming down the hall to where the bedrooms were. That is when the guy opened fire. He perceived a very real threat to his well being by a group of intruders. He had know way of knowing their intent, but did know his family was in danger. No doubt the legal system found that he was justifiable in fear for his life.
Personally, I don't believe in protecting property with lethal force. That is my call. However, I live in Texas and I very much appreciate having the right to use lethal force in certain types of property-related circumstances. Like carrying a gun, it is an option I like to have at my disposal and that I get to make the decision on and not some politician several hundred miles away making it for me.
All in all, I would say that there are some very real risks for those people who wish to commit crimes against their fellow humans and the risks may include serious injury or death. The stakes can be very high whether the criminals understand that or not.
