The Fifth Amendment states that "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."
In simpler terms: The Fifth Amendment imposes restrictions on the government's prosecution of persons accused of crimes. It prohibits self-incrimination and double jeopardy and mandates due process of law.
Did you kill that man?
I would like to speak to my lawyer.
This man was found to be a murderer after his case was taken to trial. Although, he did exercise his constitutional right by not talking to the police about his crimes.
