The act of invoking the Fifth Amendment to the U.S. Constitution allows a witness to decline to answer questions when the answers might be self-incriminating. This right protects individuals from being compelled to provide testimony that could lead to criminal prosecution. For example, during a trial, a defendant may refuse to answer a prosecutors question if the answer could implicate them in the crime.
This protection serves as a cornerstone of the American legal system, safeguarding individuals from coercion and ensuring due process. It acknowledges the presumption of innocence and places the burden of proof on the prosecution. Historically, this safeguard developed to prevent forced confessions and to protect against governmental overreach. It allows individuals to avoid contributing to their own conviction, ensuring a fairer balance of power within the legal process.
