We’ve all heard the concept of taking or pleading “the fifth {Amendment}” in court but there is more to that amendment than simply not testifying against yourself.
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 offence 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 Grand Jury which must indict for capital crimes in in addition to, not in place of, a jury of peers that all other criminal cases receive. The only exception in this grand jury is military courts in time of actual service. This amendment also contains the provision against double jeopardy (I wonder if that ever worried the game show hosts) although that protection only extends to criminal cases – civil cases may be brought multiple times for the same offense. (I guess that would also cover the game show. 😉 ) It also appears that a person might be compelled to witness against themselves in a civil case. The statement that we cannot be deprived of life liberty or property nor have property taken for public use without compensation seem to stand as a second bulwark against unreasonable seizure as protected in the fourth amendment.
