The correct answer is "Having been suspected, accused, or convicted of a crime."
Most of the due protections listed in the United States Bill of Rights deal with the fair application of the law to people in the following situation: "Having been suspected, accused, or convicted of a crime."
In this case, the 6th Amendment refers to the right to a speedy trial, to be informed of the charges, to confront witnesses of the incident, lo have a lawyer to be represented in court, or to call witnesses.
Let's remember that the Bill of Rights is the first ten amendments to the United States Constitution. It was drafted by federalists James Madison as a way to facilitate the approbation and ratification of the Constitution when Antifederalists such as Thomas Jefferson opposed the formation of a strong central government.
