Well, if your happy to increase your chances of dying, go right ahead. Acting sensibly can also turn a potentially fatal one into a survivable one, sadly, you will never be able to test that out. Personally, I leave the hero stories to the comic book writers. I will leave you to your personal fantasy of taking down heavily armed aggressors rambo style. It's patently obvious that gun ownership for so called self protection reasons and fantasies of being a hero go hand in hand. For the insecure, it proves a powerful psychological technique to give them a feeling a pseudo sense of being powerful and strong.
My dad always said to me, if something doesn't sound true, it probably isn't true.
You just have to be trolling, no one could keep giving examples based on what "might" happen in a given situation.
Having a gun, not having a gun, could end up with you dead, all the statistics in the world isn't going to change the outcome of your individual incident.
If guns didn't exist then no one would get shot with one.
It's not a difficult concept to understand.
Guns do exist and people do get shot, hardly a surprise either.
Now as guns have been invented you had better work out a viable solution to your problem but you need to add the existence of guns into your equation.
