Ok. Well, can't replace Thomas Jefferson in education. Anyway had something for u, it is about the Bill of Rights, "...independant tribunals of justice will consider themselves in a pecular manner the guardians of those rights; they will be an impenetrable bulwark against every assumption of power in the legislative or executive; they will be naturally led to resist every encroachment upon rights expressly stipulated for in the constitution by the declaration of rights.  Beside this security, there is a great probability that such a declaration in the Federal System would be inforced; because the state legislatures will jeaslously and closely watch the operations of this government, and be able to resist with more effect every assumption of power any other power on earth can do; and the greatest opponents to a federal government admit the state legislatures to be sure guardians of the people's liberty. ..." Can u think of an example the principle failed?
