First, I can find the 176 justifiable homicide by civilian reference, but you're going to have to be more specific as to the 2300 killings during arguments with firearms, there's too many tables for me to find it readily.
The data was taken from the tables "circumstances by weapon" and "circumstances by relationship".
Of course you can use the gun defensively, but in the theft example you only cause that the crime robbery is replaced by the crime attempted robbery if you can stop him. Deterrence is the only impact of a gun that would actually prevent crime.
There are four possibilities in the theft scenario (I think the most likely scenario to be hit by crime in your home) These scenarios have as prequesite that both of you know that the other person is present (you are not asleep) Usually a thief want to be sure that nobody is at home, so the following examples are just dealing with less than 50% of the cases.
1)Both are unarmed: he probably will run away
2)You are armed, he is unarmed: he will either run away if he thinks that you will not shoot at an unarmed and risk to hit him severly, because then you also commit a crime or he will give in and be captured. But: how many thiefs come unarmed?
3)He is armed, you are unarmed: he will point the gun at you, keep an eye on you, force you to give him some more money and leave. He will not shoot you, he came for theft (criminals have some ethics, too)
4)Both are armed: both of you have the gun drawn as you both hear the other person. The robber will less likely run away than in scenario 2 because he has the gun as advantage. Shootout, you can get killed or at least severely injured, as likely as the thief
Lets suppose you have a gun and only 2) and 4) can happen.
How many thiefs have no gun (lets assume 33%), how many thiefs will run away if you have a gun and they have none? Lets say 2/3 dont run. In 11% of the scenarios where you have a gun the thief will get away by running, in 22% he will be stopped and in 33% insured or shot.
In 33% of these cases you will get heavily insured or shot and he will get away.
I dont see how you can be shot if you have no gun. You will hide yourself and stay calm, if the thief notices you you will be forced to help him or roped up. The insurance will pay.
Neither did the gun prevent the thief from entering your home nor did it increase the chance of survival (66% instead 100%). He will less likely get away firsthand if you have a gun with 44% probability instead of 100%, but there is the police to solve crimes (don´t know % of theft cases solved).
Hope I made my points clear with this example.
