While that is a tough spot to be in your wife could have got back at her attacker, seeing as though she had the other woman’s wrists as she was pulling hair your wife could have done any of the following, stomped her foot on her attackers, turned toward her attack and either punch , or claw at her breasts of attacker, she could have side stepped and tilted her body frame to left or right and slammed an elbow back into attacker, or lastly snapped her head back and head butted her attackers face with back of her head. One thing any woman she know is never just assume or think your in to bad a spot to not try to get of. Yes her attacker could easily control your wife and bring her to the ground but if your wife was attempting to get free it would have been harder on the attacker to just hold her by the hair. Personally having had my hair yanked from the back like that by a bitch, i wa able to spin into her and slammed a fist to other woman’s face which put a quick end to her hold on me.
