The Fifth Amendment of the U.S. Constitution provides, "No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a grand jury, except in cases arising in the land or naval forces, or in the militia, when in actual service in time of war or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation."
The Fifth Amendment was created because the Founding Fathers wanted to protect basic rights of the accused. They objected to many of the ways they were treated by the British in matters of crime and justice. Hence, the Fifth Amendment provides for many protections from unfair methods of prosecution and investigation.
