Which right is guaranteed by the Sixth Amendment?

The Sixth Amendment to the United States Constitution guarantees several rights related to criminal prosecutions, one of which is the right to a speedy trial. This right is crucial for ensuring that individuals accused of crimes are not subjected to prolonged detention without trial and that they can present their defense in a timely manner. The underlying purpose of this provision is to promote justice and prevent unnecessary delays that could harm the accused's ability to prepare their case, witness testimony, or the availability of evidence.

While the other options mentioned are important rights, they pertain to different amendments or legal principles. The right to bear arms is protected by the Second Amendment, the right to privacy is not explicitly stated in the Constitution but has been inferred from various amendments, and the right to free speech is guaranteed by the First Amendment. Therefore, the recognition of the right to a speedy trial as part of the Sixth Amendment emphasizes the importance of expedience in the judicial process for those facing criminal charges.
