I have no problem with the judicious use of deadly force to defend you and your family.Trying to subdue and capture some cracked out motherfucker in the middle of the night is a good way to become a victim.. that's all I'm saying.
I had a break in about 2 years ago, almost shot the kid. I recognized him at the last second as he was standing at the bottom of my stairs pointing something up at me. He's the luckiest guy I know because he was a split second from being a stain on my floor. I'm glad I recognized him, I worked with the kid for 3 years but he'd never been a friend or in my house. He was wasted and didn't know where he was, smashed a window on the door to get in.... My daughter had been sleeping on the couch when he came in and he scared the shit out of her.
It took months before my wife and kids were able to sleep decent, every little noise at night would wake them up in a panic. It's not something people should have to endure. Your house is your castle and you should feel safe in your home.
The story you share here about recognizing the kid breaking in is what I urge people to be aware of: very often a family member or friend, sometimes drunk, sometimes mentally ill and confused, finds their way into your home in the middle of the night, and you end up blowing them away. I can't count how many times I've read awful stories like this - I think there was one where a deputy woke up to someone in his bedroom, and shot at the shadow, well turned out it was his wife. Another similar one, this guy killed his 5 year old granddaughter. Be sure you identify who it is as there's a very real chance they're someone close to you.
