Another quote:
"Gatineau police said it does not recommend confronting robbers, and instead recommends calling 911 and getting a good description of the suspects."
What that quote infers is they prefer that citizens don't defend themselves and prefer to leave that up to the police. I'm not sure I would just take notes while a couple of knife-wielding thug stab knives at me. Of course, you take a chance when you defend yourself, but you also take a chance when not resisting. 1 out of 12 robberies end up with non-resisting clerks receiving serious injury (broken bones, head trauma, rape, death). Are the odds better if you shoot? Not sure. The odds are better if you have a gun, though. You don't need to shoot.
There is a reason working in a convenience store is dangerous! I can't remember where I got the "1 out of 12" statistic, though.
But when you start shooting, who knows what will happen? Even if you take down those two, who knows how many more may be out there? It is a possibility your gun will jam. You may hit someone in the background. Every situation is different. I like to run away when I can. I never assume that my gun will always work, that I'm smarter, faster, more alert, etc., than my attacker(s).
Van-Tramp, you said, "And to play devil's advocate, handguns rarely stop attackers immediately too. More often then not, an attacker can take multiple hits from a handgun and still finish killing you before he bleeds out." That is statistically incorrect. Below is an authoritative link that shows the effectiveness of using a gun to defend oneself.

However, you probably meant when you actually shoot. In this paragraph, I'll leave out how simply presenting a gun overwhelmingly stops more attacks than not. Incapacitation is more about placement or other factors: Is the attacker physically fit? On drugs? In a rage? Etc. Half of head shots of any caliber are one stop shots. 25% to 30% of any caliber take two shots to incapacitate. I couldn't find out how fast that incapacitation happened, though. Shooting someone isn't like TV. It isn't uncommon to think you haven't been shot, but find out later that you actually were shot by your attacker.
Shooting to stop a lethal threat is a serious matter. I just wanted to give a bit more info to help those of you who are interested in what the best way is to survive a lethal threat. I can't answer that; only you can.
