Wait.... he ran off.
She didn't kill him, isn't that a good thing?
If you understood how to defend one's self, you would understand that it is a
lucky thing that this woman and her two children did not get injured. She was out of ammo, but her attacker was not yet disabled. In this particular case, she did not incur injury. However, the truth is that the moment she ran out of rounds she was in grave danger. If the attacker had even a slight knowledge of guns, he would have known already that she was out of rounds, and would not have believed her threats to shoot again. If he had been carrying a gun himself, he would have likely used it. Even without a gun, if he'd known she was no longer armed, he could have easily used his crowbar to attack her. She had seen his face, she could now identify him, she was therefore a the kind of threat to him that often prompts an attacker to kill a victim.
Using a firearm for self defense is a very serious and grave responsibility when one chooses to go that route. When doing so, one has a huge responsibility to learn and understand the fundamentals of using a gun against a human being, and how to use it effectively. In any form of self defense the goal is always the same: Disable your attacker so that they are
incapable of continuing to attack you. Anything short of that, you are failing to defend yourself fully because anything short and you cannot be sure that you will not be injured by your attacker. Failing to disable your attacker, and you are left with nothing but
luck to hope that he stops his attack.
Using a gun can be an extremely effective way to disable an attacker. It allows you to remain at a distance, which helps to prevent an attacker from engaging in hand-to-hand combat or from using melee or edged weapons. When practiced upon, competency can be much easier to achieve that through hand-to-hand defensive techniques, or competency with other weapon types. When used correctly and with the correct ammo, it can provide significant stopping power. It is the best way to provide personal self defense in almost every possible scenario.
All the same, it bears with it great responsibility, as I said, because it cannot be used frivolously. In order to
disable an attacker, you have to be willing to
destroy, i.e. kill the attacker. That does not mean that once you've taken an attacker down, you should "finish him off" with a round to the head. It means that you drop him, and stand ready to fire again if he doesn't stay down. If he tries to get up, YOU HAVE TO ASSUME, that he's going to try to attack you again.
