OP - what it really comes down to, in this state, is that you have to determine if the use of your firearm in a situation, is worth potentially spending the rest of your life in jail.
My wife and I have discussed this at length and most people have a plan. The only thing that is worth spending the rest of my life in prison is the lives of my wife and kids.
We have agreed that in the event of a late night home invasion, my wife will call 911 and try to get both kids into the farthest bedroom. I will position myself at the top of the stairs. I will gladly watch someone walk out with anything they want, TV, laptop, iPad, anything they deem worth stealing. It's all just stuff and can be replaced.
However,they are NOT coming up those stairs.
You also have to consider a home invasion during waking hours. You are hanging out watching the game, and 2 or 3 armed men break down your door.
As mentioned many times on this forum, home defense needs to be applied in layers. In most cases/scenarios, the use of a firearm can be a last resort that is avoided. In my opinion, a good dog will thwart most attacks. You don't need a mastiff or rotweiler either. A golden retriever, lab, or medium sized mutt, will keep most people away. Secure entry doors are a must. If it's very hard to get in, and the dog is barking most criminals will select a softer target. Cameras and alarms are great, but can't stop a determined assailant. A panic button with a loud siren is most effective.
So, the dog is barking, the alarm is blaring and they can't get through the door. You either have something very valuable inside, the assailant/s are extremely determined or you have managed to attract attention from a serious criminal group.
