Had the gunman simply displayed a weapon while ordering the clerk to clean out the register there would have been no need for the customer to intervene.
Could have shot the clerk before , or as he was leaving.
Point a weapon at me in commission of a crime, or point a weapon at me illegal - I see that as a threat to my life. Same as if I see a gunman pointing a gun at someone illegally, or while committing a crime - the gunman can shoot an individual or individuals as the gunman leaves- it has been done before ; maiming them for life or killing them.
Chicago is not gun friendly, but where I am from - I'd shoot the gunman twice then go order a meal.
Point a gun illegally, or during a crime ; and I would shoot the perp or perps.
