I never said "he deserved it", merely postulated it as a likely scenario. Similar to the Lorena Bobbitt case, I'm speculating that it may have been the result of continuous abuse by the husband. I didn't bother looking up the case, though. If I was wrong and the woman was the abuser, I apologize.
I will grant you that men are much less likely to report such abuse, generally as a matter of pride I would think. But women who do report being abused aren't guaranteed to get protection, either. I know of one woman who called the police on her abusive husband only to have the responding officer stand out in the yard talking and joking with the husband, then driving off, telling him not to do it any more, without even talking to her!women are as likely as men to be guilty, just much less likely to get caught.
