This is a quote from my local paper today:
"Dec. 21 - A man with a gun who tried to rob The Final Fade barbershop on North Plum St. got a suprise when a barber and a customer pulled out guns and fired at him. Police do not know if the man was hit"
I think there is no clear answer, it all depends on the each situation at the time.
