The correct answer is: be represented by a lawyer in court.
The Sixth Amendment of the United States Constitution guarantees a citizen the right to a speedy trial, a fair jury and an attorney if the accused person wants one. If a person can not afford an attorney, a state ( free ) attorney would be made available to him.
The Sixth Amendment was put into the Bill of Rights by James Madison on September 5, 1789. The rights in it apply to all states. Any accused person may represent himself in court but only if they are mentally stable.
