If there is a reason to present a firearm, it is to stop the threat permanently.
Shooting to wound is not stopping the threat permanently.
Shooting to warn uses precious ammo and presents other dangers to the shooter.
Presenting a firearm without the intent to permanently stop the threat (as in a bluff), creates other problems for the presenter.
