A case that's been discussed extensively by the Iranian media is that of the woman who was blinded and had her face disfigured with acid by a man who's advances she'd rejected. By Iranian Quranic law of eye for eye she has the right to blind the man by injecting his eyes with drops of acid.
Though these cases or commonplace in Iran, where usually the family of a killed one is asked if the killer should be put to death or bloodmoney should be paid to spare his life, it's the possible blinding of a person that has caught the public's attention and has sparked the debate.
One of the articles written a while ago was against this system of revenge killing and maiming, to which the sister of the victim wrote this response. It was very difficult for me to read, as the writer sympathetically argues for the right of her sister to blind her attacker.
