I really disagree. Someone threatens me to kill me, I make sure they don’t get up to finish what they intended.
To believe anything else is stupid.
A law enforcement officer, a deputy for Los Angles County, long ago told me that if anyone points a gun at me or attacks me with a knife, that person intends to kill and I have every right to kill them dead in self defense. Particularly, make sure they can’t come after you and finish you off.
That advice was way back in 1964. A lot has changed since then, but I would rather be in a court judged by twelve of my fellow citizens that buried six feet under because I showed mercy to a God damned criminal!
I remember being so afraid after the Rodney King riots... I wanted to get a gun or a taser and friends who were LE told me that I had to arm myself with something that would completely stop the attacker or it would be used against me. They advised against a taser and told me to learn to shoot and get a concealed carry permit. This coming from police!!!! You shoot to kill...you are not an expert... go for the most damage because it can mean your life.
