We're in agreement on that. But when in pursuit of an armed & dangerous individual, armed with a gun, I do believe lethal response in self-defense or pursuit of neutralizing the threat is authorized. If the killer is killed in an armed standoff with police, while not the goal, I'm going to call that a bonus.

I think it is a lapse in moral judgment to command others to act in ways that we wouldn't act ourselves...I think most people, pursuing an armed & dangerous killer, would want a gun & permission to use it when their lives are threatened. Tasers, stun weapons, and other non-lethal forms of detainment require getting uncomfortably close to the armed & dangerous person.
