Again I say you had better read up on the laws in your state.
In most states, the law is that you have a reason to believe your life is in danger if you are in the house while it is being broken into.
The logic is that you have no way of knowing whether your door is being breached to get at your valuables or to get at you.
On the other hand, if you arrive at your house while a burglary is in progress, you can not shoot unless the bad guy is armed and a definite threat to your safety and you were unaware that he was in your house.
The logic being that he did not break in to hurt you, but rather to steal your stuff knowing you were not home.
That is based on the philosophy that no matter how much your stuff is worth, maybe even hundreds of thousands, the life of the most unworthy human scum is worth more.
The law is especially hard on those who could see from the street that something was amiss, a strange car in the driveway, the door standing open, a broken window, etc., and did not withdraw to a safe distance and call the cops.
Entering your house knowing a burglary is in progress is very bad judgement both from a legal standpoint and from the standpoint of personal safety.
Arguing whether the laws are just will not save your butt in court. The prosecution will only use your opinion against you to show you care not what the laws are.
As for the castle doctrine, so often quoted by those who have no idea what they are talking about, it does not negate any of the requirements for a lawful self defense shoot. In reality, all it does is eliminate the requirement that you attempt to flee plus it protects the lawful shooter from civil lawsuits. And it defines those places where it can be claimed.
I am not a lawyer. Just someone who carries and realizes how treacherous self defense laws are.
We need to form a common sense club. Your post is spot on and its scary to see how many seem to not fully comprehend the consequences of even a justified shoot, much less a borderline or bad shoot.
Man, that was good. If I may, I would like to add that one cannot instigate the event [confrontation] then claim the protection of the law. a guy in Florida thought he could do that. A Jury informed him that was not the case.
