You think shooting to wound a cop with 30 or so years on the force trying to assist is good shooting?
Maybe you could watch “Sgt. York” or “Band of Brothers” for a refresher on good and purposeful shoooting.
Better still, take up your argument with an NRA representative or a local gun range instructor. Wee if they agree.
Replace “gun” in the story with baseball bat, golf club, fireplace poker, brick, rock, knitting needle, butcher knife or any other inanimate object that might be used in a defensive scenario.
Based on your logic, she should not be allowed to possess any of those items.
