Evidently you never had your Mother "restrained" from leaving an abusive situation or have your child watch the male female relationship as a basis for his or her future relations. It is bad for all concerned and men should get over the idea of trying to physically control women that they can't subude with abusive language.
Did they the prosecutor go to far? Maybe. But please, do not downplay the event to the women and children that are wondering if they should report their situation to the authorities.
