Answer: "In all criminal prosecutions, the accused shall enjoy the right to ... have the Assistance of Counsel for his defence."
Step-by-step explanation:
The Supreme Court in this instance is saying that the right to a legal counsel is a fundamental aspect of the trial process in the United States even if this is not the case in other countries.
The Supreme Court is therefore saying that in all criminal prosecutions, regardless of the heinousness of the crime committed by the accused, they must always have the right to a counsel as this is the only way to ensure a fair trial.
