who said i defend your right to say it
Evelyn Beatrice Hall In The Friends of Voltaire, Hall wrote the phrase: "I disapprove of what you say, but I will defend to the death your right to say it"[4] (which is often misattributed to Voltaire himself) as an illustration of Voltaire's beliefs.[5][6][7] Hall's quotation is often cited to describe the principle of freedom of speech.
Right to silence The Fifth Amendment to the United States Constitution provides that no person shall be compelled in any criminal case to be a witness against himself or herself.[72][73] At trial, the prosecution can neither call the defendant as a witness, nor comment on the defendant's failure to testify.[74] Whether to testify or not is exclusively the privilege of the defendant,[75][76] although defendants were originally not allowed to testify on their own behalf at all.[77] An 1864 appropriations act allowed defendants to do so while removing race restrictions,[78] and the 1987 Supreme Court case Rock v. Arkansas established a constitutional "right to take the witness stand."[77]
