Are you suggesting he was justified to hit his wife?
No I am not. But I don't like zero tolerance and the insanity that goes along with jailing people in this day and age. No marks on her. Look, if she had bruises or lacerations, sure, send the puke to jail.
In this case, the legal systems should be able to determine that the wife assaulted the man's faith and his eardrums, he reacted poorly. To me, she's as guily as the husband, maybe more so because she started it with her illegal assault.
