Nonetheless, the laws relating to the use of force are what they are.
I agree with you. Reading these posts, I can see that we are discussing two different things:
1) What is the correct legal action to take if someone has already taken your property
2) "It's my property and I have the moral right to stop someone from taking it anyway I can"
The OP was asking about #1. At some time or other, we have all thought about #2, fantasized what we would do if it happened to us, replayed various scenarios, and probably realized how easy it is to get very angry when someone violates us by stealing our property.
All I can say is that if you want to stay out of jail, think about #1 and forget about #2. This is complicated because there is such a thin line between justifiably shooting someone vs. it being a felony. Just pointing a gun at someone is usually considered assault. You have as little as milliseconds to decide what to do and act. The jury will have hours to dissect your actions and will wonder why you didn't behave the way they have decided you should have. Shoot someone in the leg? Just wound them? No instructor will tell you to do that. If you shoot at someone, you shoot center mass until the threat they pose is stopped, that's what they teach because if you shoot to wound, you will probably miss.
Laws generally say that you are justified in using deadly force to stop imminent grave bodily harm or death. Many states say you can use force to stop certain felonies like robbery and arson. What happens if after you shoot someone the police or jury decides they weren't committing such a felony?
