"Prior to any questioning, the person must be warned that he has a right to remain silent, that any statement he does make may be used as evidence against him and that he has a right to the presence of an attorney, either retained or appointed"

This quote by Earl Warren is describing the Miranda Rights, which are a set of rights that should read to an individual who is being questioned by law enforcement. The quote is highlighting that prior to any questioning happens, the person should be informed of their right to remain silent, that any declaration they make can be utilized as proof versus them, and that they have the right to a lawyer. This is to make sure that the person is aware of their rights and that they are not being pushed into making a declaration. The Miranda Rights are an important part of the criminal justice system, as they safeguard the rights of individuals who are being questioned by police.
