Matt Cherry explains the role of the US Supreme Court.
When American politicians and police officers enter into public service, they do not swear an oath to the President or to Congress. Nor do they pledge their obedience to God or the Nation. Instead they swear an oath to "support and defend the Constitution of the United States against all enemies, foreign and domestic".
The Constitution was ratified in 1788 and the first ten amendments to the constitution, known as the Bill of Rights, were ratified in 1791. Amendments to the Constitution must be passed by a two thirds majority in both houses of Congress, plus by the legislatures of three quarters of the States.
