Let them come into your home before opening fire for a better legal outcome.
Once they are in your home, I think most juries would not press charges.
I agree that fear makes people a little rash, and understandably so.
I know what the law says, but three armed intruders (do you know at that time they are not armed?) are trying to break in your front door with extreme violence. You’re going to wait for them to enter before shooting? Possibly three people are going to come through your door shooting. Are you good enough to get all of them? If not, You’re dead and your wife and kids are at thier mercy. I would take my chances with the law. Better to be tried by twelve than carried by six.
