The Bill of Rights is one of the (3) founding documents defining the United States of America. Some of the colonies would not ratify the constitution because they thought that there needed to be more protection against the possibility of tyranny. Every amendment in the Bill of Rights guarantees a right of the citizens, and is a limit of the authority of government.
