Badger, you seem to be under the impression that "The Law" isn't itself a product of personal and individual values. That strikes me as obviously untrue.
Also, jury nullification isn't illegal. Aside from the obvious fact that there is no statue outlawing it, it has a long precedent in American jurisprudence and English Common Law. You protest that an individual is unfit to contradict decisions already made by the court system, yet the court system itself had upheld the right of jury nullification again and again:
So, by opposing the right of jury nullification, you yourself are contradicting the established opinions of the judicial system and are guilty of exactly what you accuse nullifiers of.
