Answer 2

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.

As you can see, it covers many rights, but the most commonly used or known part is the right against self incrimination; when accused of a crime by the state, you can't be compelled to testify against yourself. Hence the "You have the right to remain silent..." part of the Miranda Warning...
