The only decision the cops need to make correctly is "to shoot or not to shoot." Once the decision to shoot is made, then (and rightly so) there is no "to kill or not to kill" decision.
Just to take it one step further, the police are actually trained to shoot to stop. If that means the guy is killed as well, too bad. But the primary goal of any police shooting is to stop the person from continuing his actions. Whether he is wounded or killed or simply knocked out isn't important.
