With a gun in each other's face the good guy is lucky to be alive to tell the story.
It is easy to say what one would do until you are faced with the same decision. The good guy had courage to not pull the trigger. He also had the frame of mind to pull his weapon. The sad thing in this will be the would be robber is still out there.
Lucky he made it but hopefully the robber doesn't do this to someone who doesn't carry....
