The Bill of Rights must be subjected to no 'interpretation' of any kind except in terms of the original intent of the Founding Fathers, a group of individuals who had just barely defeated the most overbearing, ruthless, and dangerously violent government in the history of the world. Even the British people were having trouble with it at the time.
The Bill of Rights represents an historic bargain between those who advocated a strong central government - and whose political ideas and wishes are expressed in the main body of the Constitution - and those who did not. Without the Bill of Rights, the Constitution ceases to be valid; any legitimate authority that derives from it ceases to exist.
