There is the rare situation where it would make sense, but you would not want to shoot.
There is also the situation where you are out of ammo, but still confronting an immediate assailant.
And today, this guy woke up, made his coffee, and is likely having an ok day. He isn’t facing a homicide investigation, and hoping the DA sees it his way. Clearly something told him he could handle it this way and quickly had the bad guy on the run.
That really is the difference between us and the murderers. We do it when it really is unavoidable, not when we can simply justify it.
