Yes, the Old Testament said "eye for eye". So did the Torah (which is what you're really talking about when you speak of the first five books of the Old Testament). So have countless research papers that focus on the Code of Hammurabi. So have many posts on slashdot, regarding this story. Why is the Christian Bible any more relevant here than any other set of writing about the concept of justice in the form of proportional retribution? Why did you write "Even the Old Testament said" and not "Even Hammurabi said" or "Even the Torah said" or "Even Dr. Charles F. Horne said"?
As an atheist, you should be ashamed to be so thoroughly indoctrinated with Christian belief. Christianity has a long tradition of co-opting pre-existing beliefs, practices, and philosophies, and claiming them as Christian. Your original post only furthers this tradition. What we're arguing about amounts to whether the definite article "the" is Christian, since the pages of the Christian Bible are littered with it. When discussing the definite article, it's odd to bring up the Christian Bible, since although it makes heavy use of the definite article, it is neither the originator of the concept nor a particularly interesting instance of its usage. Ditto "eye for eye".
My point is furthered by the fact that the comments under this story mention "eye for eye" several times, but always in the context of Christianity. One of the threads even devolves into a discussion about a parable written of by John (which is perhaps more relevant or interesting than mentions of the Old Testament). Not a single mention of Hammurabi, the originator of the concept. You don't think Christianity has "claimed" this concept yet? You say you're an atheist, but here you're playing on the Christian team.
