Answer:
protection from self-incrimination
Explanation:
The Fifth Amendment of the United States Constitution was passed in 1791. It started among other things 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..."
This implies that an accused has the right not to reply to the police questions both while in custody or court. The purpose is for the protection from self-incrimination that may arise.
