In many countries the presumption of innocence comes with the corollary that the accused must have the right to remain silent and there must be no need for him to participate in any way to the acquisition of evidence. However, while this happens in some countries such as the United States, the presumption of innocence does not necessarily imply the right to remain silent. For instance, in France the right to remain silent is granted only during the judicial investigation,[3] while during the investigatory detention (garde à vue) conducted by the Police such right is not envisioned.[4]
