Because castle doctrine and slow police response times.
On top of that, it's hard to say how someone is going to perform or react in a scary scenario like that. I would like to imagine that if I ever had to protect myself in that manner from a home invasion that I would not shoot to kill, but just immobilize the person. But I can't say if the combination of fear and adrenaline would allow me to be on point like that.
You shoot to STOP the threat.
Right, but I don't want to kill someone if I have an opportunity not to.
Especially a burglar. To go on a little rant... I have a good friend that is a criminal defense attorney and another that is a DA. Both have said to me that 90% of the people they come across are people of happenstance and bad luck. People get desperate when they are hungry, scared, have no home, or a secure life. That can drive people to do all kinds of 'bad' things that they may not have ever considered doing if they had their basic needs met.
Anyway, that perspective has given me a lot of empathy towards people who commit certain crimes.
