Bill of Rights
The 5th Amendment
The Fifth 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 5th Amendment in other words
The 5th amendment guarantees the right to a grand jury. It also prevents double jeopardy. The fifth amendment protects you against self incrimination.
