Which right is NOT guaranteed to an accused person during a criminal investigation?

The right to a speedy trial is not guaranteed during the initial stages of a criminal investigation. Instead, this right becomes applicable once formal charges have been filed against an individual. The concept of a speedy trial is aimed at preventing undue delays in the judicial process; however, it does not initially pertain to the investigation phase, where the accused may not yet be formally charged.

During a criminal investigation, the accused does have important rights, such as the right to remain silent, the right to legal counsel, and the right to be informed of the charges if they are formally charged. However, until charges are brought forward, the accused may not benefit from the protection of a speedy trial, as the timelines for this right activate only following an official indictment or charge. This contextual understanding is crucial in recognizing the specific stage of the criminal process being referred to concerning the rights of an accused person.
