Does your answer represent the libertarian point of view, conventional legal reality, or what? Just so you know, my thinking, which is implicit in the question posed, is strictly confined to the morality of self defense. I'm open to another point of view. But I don't think we've completely delegated to the government absolute responsibility in the matter of apprehension of criminals who are in the process of conducting a crime. Does hot pursuit automatically a count as a strike against self defense?
It isn't self defense if you are in hot pursuit, you have become the aggressor. Your right to use deadly force ceases when your life (or family and friends) is no longer in danger.
You describe yourself as a libertarian. If you confront a felon who is in possession of your personal property - and attempt re-possession of the property - and said property is a deadly weapon - and the felon struggles to maintain control of the property - why should the felon be given the benefit of the doubt as to intent?
You don't have the right to use deadly force to recover personal property. Do you think that if your neighbor has stolen something from you that you have the right to go into their house and shoot them to recover it?

Mostly conventional law. In this case though it is in line with my libertarian view. The basic rule is that you can only use deadly force if you are threatened with deadly force. If you go out and become the aggressor (taking the gun from someone) and shoot them, you didn't act in self defense.

You cannot use deadly force in the apprehension of a criminal. The cattlemen who rounded up the rustlers and hung them were guilty of murder. But they had every right to apprehend them (including the threat of deadly force) and take them to a legal authority. The downside is that if you are mistaken, then you become guilty of kidnapping, etc.
