Fifth Amendment Self-Incrimination Protections
I. Overview
The Fifth Amendment to the U.S. Constitution includes the Self-Incrimination Clause, which states that no person “shall be compelled in any criminal case to be a witness against himself.” This protection means:
Individuals cannot be forced to testify or provide evidence that may incriminate themselves.
Applies in both criminal trials and custodial interrogations.
Extends to testimonial evidence, not physical evidence.
Protects natural persons, not corporations.
II. Key Legal Principles
The privilege protects against compelled testimonial communication.
Invocation of the privilege must be explicit; courts generally require clear assertion.
Applies during custodial interrogation and trial testimony.
Miranda warnings (Miranda v. Arizona) inform suspects of this right.
The government cannot penalize someone for asserting this right.
III. Landmark Cases on Self-Incrimination Protections
1. Miranda v. Arizona, 384 U.S. 436 (1966)

Issue:
Does the Fifth Amendment require police to inform suspects of their rights before custodial interrogation?

Significance:
Established Miranda warnings, a procedural safeguard to protect the Fifth Amendment privilege.
2. Malloy v. Hogan, 378 U.S. 1 (1964)
Facts:
Malloy refused to answer questions during state criminal proceedings, invoking the Fifth Amendment.
Issue:
Does the Fifth Amendment privilege apply to the states through the Fourteenth Amendment?

Yes. The Supreme Court held the self-incrimination clause applies to state as well as federal prosecutions.
Significance:
Incorporated the Fifth Amendment protection against self-incrimination to the states.
3. Schmerber v. California, 384 U.S. 757 (1966)
Facts:
Police forcibly drew blood from a suspected intoxicated driver without consent.
Issue:
Does the Fifth Amendment privilege protect against compelled blood tests?
Holding:
No. The Court distinguished between testimonial evidence (protected) and physical evidence (not protected).
Significance:
Clarified that the privilege protects testimonial communications, but not physical evidence like blood samples.
4. Kastigar v. United States, 406 U.S. 441 (1972)
Facts:
Kastigar was granted immunity but refused to testify, citing Fifth Amendment.
Issue:
Can the government compel testimony if it grants use and derivative use immunity?
Holding:
Yes. Immunity that removes risk of self-incrimination overcomes the privilege.
Significance:
Outlined standards for immunity that can compel testimony without violating Fifth Amendment rights.
5. Salinas v. Texas, 570 U.S. 178 (2013)
Facts:
Salinas voluntarily answered some questions but fell silent on others before arrest.
Issue:
Is a suspect’s silence before arrest or Miranda warnings invoked protected under the Fifth Amendment?
