Video footage of a group of teenage girls savagely attacking a woman in Philly. It seems that city has seen the most use of the teen mob attack.
My takeaways from the half of the video that I was able to watch are: 1) the victim noted that she heard the attackers coming up behind her, and said that she is vigilant about being aware of her surroundings; 2) By the time she turned around, the attack was already initiated; 3) She was on the ground immediately.
To address the first takeaway - being aware of your surroundings is paramount to your safety. The consensus is that picking up on an attack and avoiding it is the best option, and will have a better outcome than a fight and/or shooting your attacker(s). With that said, you cannot count on vigilance to always win the day, so be prepared.
On the second takeaway, even if you spot an attack before it happens, you may not be able to prevent it regardless, so be prepared.
Third takeaway - learn to fight on the ground. Most physical fights end up on the ground anyways, and I am as guilty as any about doing my practice shooting while standing. Most of that has to do with where I shoot; I can shoot safely with a handgun or rifle from a bench, but not up at a target while I'm on the ground. Shooting school is where you would learn the techniques. I would imagine that it's difficult to get a gun into play while a group of people kick you in the head while you're on the ground, but it's a probability that could happen, so be prepared.
Also, just because attackers are female does not mean that they aren't capable of inflicting severe or fatal injuries. A girl can end your life just as easy as boy or man, especially when you're on your ass in a parking lot and there's six of em'.
