evidence: Explanation: This amendment is one of the most ignored in the Constitution. It is a protection against quartering, using private homes to house military troops in times of war or peace. The provision was included in the Constitution because the practice had been used by the British in the Colonial Period, but the U.S. Supreme Court has never heard a case based on the 3rd Amendment. [...] The Bill of Rights protects citizens from the power of the national government, but does it also apply to state governments? After the 14th Amendment was added in 1868, the Supreme Court interpreted this amendment to apply to the states as well as the national government. The federal courts have interpreted and applied the 14th Amendment’s "due process" and "equal protection" clauses to the states in a variety of situations. This protects citizens because it limits the ability of the states to ignore the rights and liberties implied by the Constitution’s Bill of Rights. [...] - The Supreme Court has held that the due process clause of the 14th Amendment means the states must apply the Bill of Rights.
