IANAC, but all the training I've received has taught "shoot to kill."
Shoot to injure? WTF is that? If you're in a situation where you feel killing is not necessary/justified, you ought not be using that gun in the first place.
For civilians -- 'shoot to stop' the attack is the operative phrase ... even if it takes an entire magazine to 'stop the attack'.


This stuff is way, way above both of our paygrades - as an officer AND as a civilian. We shouldn't criticize things we have very little grasp of based on having 5% of the facts that The Man has in front of him. That's good advice for all you new JOs headed for the fleet. You will all come across policies and decisions that make absolutely no sense to you and you will say WTF? Just know that most of the time, there's a method to the (apparent) madness and the guys in charge know what they're doing.
