At 54 years old with some injuries that made me give up running several months ago I am no longer in good enough running condition to outrun a group of younger attackers. Also, I have good hand to hand skills but facing multiple determined attackers is extremely difficult even for someone who is skilled. In a case like the one shown above if unarmed I would probably be faced with a decision to either curl up in a ball on the ground and try to avoid sustaining a fatal injury or simply go out fighting. I think I would be more inclined to fight to my last breath. If armed, I think using the weapon would be justifiable. Against a bunch of people the effectiveness of an armed response would depend on how focused the response is and how the crowd reacts to it. I don't think there's an easy way out of a situation like that.
