When an armed intruder is breaking into my house? Yes shooting them is in fact my first go-to defense. When someone else is intending to do harm to me or someone I love I'm not going to wait around for the police to get there 30 minutes later. All the police are going to find is my dead body by then.

He was talking in a 'naturalistic' way so I responded in kind. In reality if I found someone has stolen my home I'd call the authorities unless of course I feel a danger to my life in which case, had I not lived in the UK where guns are illegal, yes - shooting them would have been the first course of action. That is nothing to do with law or ethics, and lots to do with survival instinct.
