Chapter 7
Compulsory Self-Incrimination
Objectives
This chapter discusses two constitutional limitations on the governments power to compel citizens to
furnish self-incriminating evidence. The Fifth Amendment is concerned with testimonial self-incrimination
(i.e., compulsion to disclose ones private thoughts). Its application during custodial interrogations was
discussed in Chapter 6. This chapter provides a more complete analysis of the Fifth Amendment. The
second limitation stems from the Fourth Amendment prohibition on unreasonable searches and seizures.
Evidence taken from a suspects body is called physical evidence. Compulsory production of self-
incriminating physical evidence requires a restriction of the suspects freedom of movement (i.e., a seizure
of his person) and sometimes also an invasion of his privacy or bodily integrity. Concern for these interests
is addressed by the Fourth Amendment. This chapter builds on the Fourth Amendment principles introduced
in Chapters 3 and 4. The student should leave this chapter with an understanding of:
1. The constitutional principles that regulate compulsory production of self-incriminating testimony and
physical evidence.
7. Fourth Amendment requirements for strip searches and body cavity searches.

Fourth Amendment
o Compulsory production of physical evidence
§ 7.1 Introduction
A. There are two types of self-incriminating evidencetestimony and physical evidence.
1. Testimony refers to words or conduct that reveal what a person knows. The source of constitutional
2. Physical evidence includes just about everything else. A suspects body can be the source of two
different kinds of physical evidenceappearance evidence (i.e., evidence derived from body
§ 7.2 Fifth Amendment Protection against Testimonial Self-Incrimination
A. The Fifth Amendment privilege against self-incrimination is violated whenever the government
PowerPoint Slide 5. Degrees of Fifth Amendment Protection
Suspects have the right to remain silent during custodial
B. There are two degrees of Fifth Amendment protection:
1. Citizens enjoy an absolute right to remain silent during custodial interrogations and at their
criminal trial.
2. In all other situations, citizens may be compelled to appear and testify, but are privileged to refuse
to answer specific questions if the answer might tend to incriminate them.
a. Illustration: A and B are arrested on charges of operating a drug-trafficking ring and taken to
PowerPoint Slide 6. Prerequisites for Application of the Fifth Amendment
The Fifth Amendment states that no person shall be compelled
in any criminal case to be witness against himself.”
(1) Compulsion, (2) testimony, and (3) self-incrimination are
necessary to trigger protection.
Testimony
§ 7.3 Prerequisites for Application of the Fifth Amendment
Three prerequisites are necessary to trigger protection of the Fifth Amendment privilege against self
incrimination: (1) testimony (2) compulsion, and (3) self-incrimination.
A. Testimony. Testimony, for purposes of the Fifth Amendment, includes any behavior that, explicitly or
implicitly, reveals something a person knows.
Schmerber v. California (Part II) discusses the meaning of testimony for purposes of the Fifth
PowerPoint Slide 7. Compulsion and the Subpoena
The normal manner in which our legal system compels
testimony is by issuing a subpoena:
Court order to appear and testify
B. Compulsion. Compulsion occurs when the government threatens serious consequences unless a person
makes a statement. The threatened consequences may take the form of contempt sanctions for
disobeying a subpoena, physical harm, job loss, etc.
1. The relevant time for evaluating whether compulsion has occurred is when an incriminating
statement was made originally. The Fifth Amendment does not prevent the government from using
existing incriminating writings, records, letters, and other documents that were voluntarily
PowerPoint Slide 8. Self-Incrimination and Immunity
Absolute immunity
o Bars the government from prosecuting the witness for
C. Self-Incrimination. To be self-incriminating, the statement must expose the maker to risk of criminal
prosecution.
1. People under arrest may be compelled to furnish biographical information (i.e., name, address,
Social Security number, etc.) needed for booking because this information is not incriminating.
2. People who have already been tried for the crime to which the questions relate may not invoke the
3. People who have been granted immunity from prosecution may not invoke the protection of the
Fifth Amendment. Two different kinds of immunity are available. Absolute immunity exempts
PowerPoint Slide 9. Waiver of the Privilege
A waiver occurs when a person voluntarily answers
incriminating questions without invoking the privilege.
§ 7.4 Rules for Invoking and Waiving Fifth Amendment Protection
A. Invoking the Fifth Amendment
1. Criminal defendants have a Fifth Amendment right to remain silent at their criminal trial. They
B. Waiving the privilege
1. A waiver occurs when a person who has a Fifth Amendment privilege voluntarily testifies without
invoking it. Under Miranda, a valid waiver requires a warning. However, the Supreme Court has
2. Criminal defendants who take the witness stand waive the privilege, but only concerning the
PowerPoint Slide 10. Adverse Inferences from Taking the Fifth Amendment
Judges and prosecutors are barred from commenting that a
§ 7.5 Protection against Adverse Consequences from Exercising the Privilege against Self
Incrimination
A. Judges and prosecutors are not permitted to make adverse comments about a defendants refusal to
answer police questions during a custodial interrogation or a defendants decision not to testify at his
or her criminal trial or sentencing hearing.
§ 7.6 Self-Reporting Laws and the Fifth Amendment
A. The Fifth Amendment does not exempt people from filing government reports that could draw attention
to their criminal activity when the reporting requirement furthers a legitimate regulatory purpose.
1. The Internal Revenue Code, occupational tax laws, and hit-and-run motorist statutes are examples
2. However, citizens may refuse to comply with government reporting laws that serve no purpose
besides forcing them to disclose their criminal activity.
PowerPoint Slide 11. Bodily Self-Incrimination
The Fifth Amendment does not protect against compulsory
§ 7.7 Fourth Amendment Protection against Bodily Self-Incrimination
A. The Fifth Amendment only protects against testimonial self-incrimination. It does not protect against
compulsion to furnish self-incriminating evidence that comes from his body.
Schmerber v. California (Part II) is a good case to transition from Fifth Amendment protection
against testimonial self-incrimination to Fourth Amendment protection against bodily self
Because the Miranda rule is based on the Fifth Amendment, warnings are not required before
compelling suspects to participate in procedures that yield physical evidence, such as fingerprints,
B. Compelled production of self-incriminating physical evidence is regulated by the Fourth Amendment.
C. Physical evidence taken from a suspects body is broken down into two categoriesappearance and
bodily evidencedepending on the interests that are implicated.
1. Appearance evidence refers to evidence derived from bodily characteristics that are routinely
displayed to the public.
PowerPoint Slide 12. Appearance Evidence
Derives from bodily characteristics that are routinely
displayed to the public
Examples:
§ 7.8 Requirements for Appearance Evidence
A. The most common police procedures involving appearance evidence are: (1) station house lineups; (2)
B. Because the suspects interest in freedom of movement is the only interest invaded by these procedures,
compulsory production of appearance evidence is permitted whenever the police have constitutional
grounds to seize the suspect and detain him or her long enough to perform the procedure.
1. A lawful arrest carries authority to compel participation in all procedures that yield appearance.
C. Some jurisdictions have statutes authorizing the prosecutor to apply to a court for an order compelling
D. An illegal arrest taints appearance evidence. Fingerprint and footprint matches, positive lineup
identifications, and other forms of appearance evidence that derive from an illegal arrest will be
suppressed.
PowerPoint Slide 13. Bodily Evidence
Physical evidence obtained by (1) inspecting private parts of
the anatomy, (2) penetrating below the body surface, or (3)
§ 7.9 Requirements for Bodily Evidence
A. Bodily evidence refers to evidence derived from a suspects body by: (1) searching areas not normally
exposed to the public, (2) penetrating the body surface, or (3) removing biological or foreign
substances.
B. The following procedures involve bodily evidence: (1) removing incriminating residue from the bodys
C. Unlike appearance evidence, which involves no intrusion beyond an interference with the suspects
PowerPoint Slide 14. Schmerber v. California
Established the modern framework for evaluating the
D. Schmerber v. California (Part II). In Schmerber, the Supreme Court established the contemporary
framework for evaluating when highly intrusive bodily searches satisfy Fourth Amendment standards
of reasonableness. Schmerber was arrested for drunk driving and taken to the hospital, where a blood
sample was drawn without his consent. The sample was subjected to chemical analysis and yielded
evidence of alcohol intoxication. The test results were admitted at Schmerbers trial, over his objection
that the blood sample was the product of an unconstitutional search and seizure. The following points
should be made about the case: (1) Compulsory extraction of blood for chemical analysis constitutes
both a search and a seizure, calling for analysis under the Fourth Amendment. (2) Intrusive procedures
E. Surgical intrusions to recover evidence. Of all bodily evidence procedures, surgical intrusions under
general anesthesia are the most invasive. Because the governments need for the evidence must be
greater than the invasion of the suspects privacy or bodily integrity that will be required to obtain it,
PowerPoint Slide 15. Procedures Requiring a Warrant
Unless confronted with an emergency that could result in the
§ 7.10 Necessity of a Search Warrant to Explore for Bodily Evidence
A. Unless confronted with an emergency that threatens destruction of evidence, police should obtain a
search warrant before arranging for procedures that involve: (1) taking saliva, urine, semen, pubic hair,
or other bodily tissue or fluids; (2) penetration of the bodys surface; (3) examination of rectal or genital
cavities; (4) medical risk, or (5) significant pain, discomfort, or humiliation.
PowerPoint Slide 16. Exigent Circumstances
The exigent circumstance exception allows the police to conduct
B. Exigent circumstances exception. The exigent circumstances exception excuses the need for a search
warrant when police have probable cause to believe that incriminating evidence is present and that the
evidence will be destroyed if they delay action to obtain a search warrant. Courts have applied this
exception to:
1. Extracting blood to run tests for alcohol intoxication. However, the natural metabolism of alcohol
in the bloodstream does not automatically create exigent circumstances excusing the need for a
search warrant. Whether a warrant is necessary depends on whether one can be obtained within
2. Swabbing for residue. Because residue left on the skin after the commission of a crime can also
deteriorate rapidly, no warrant is required. Police may perform this procedure whenever they have
3. Reaching into a suspect’s mouth. When a suspect tries to swallow evidence, there is no time to get
a warrant. Police may try to retrieve it.
C. A search warrant is not is required to take a DNA swab from persons arrested for serious crimes when
the swab is taken as a routine part of the booking process. This is because the sample is taken for an
administrative purpose (to identify the person arrested through his DNA, determine whether he is too
dangerous to be released on bail, etc.), not investigatory (to obtain evidence of the crime for which he
was arrested.)
Maryland v. King (Part II). The Supreme Court upheld the Maryland DNA Collection Act,
PowerPoint Slide 17. Strip and Body Cavity Searches
Investigative strip search
o Police must have reasonable suspicion that a search will turn
up drugs, weapons, criminal evidence, or contraband
§ 7.11 Strip Searches and Body Cavity Searches
A. The term “strip search,” for Fourth Amendment purposes, refers to any [forced] exposure or
observation of a portion of a persons body where the person has a reasonable expectation of privacy.”
1. Investigatory strip search. Strip searches conducted to gather evidence require a lawful arrest
2. Jail intake strip searches. Florence v. Board of Chosen Freeholders of County of Burlington
(Part II). Blanket strip search policies requiring all persons booked into a detention facility to
3. Manual body cavity search. Searches that involve touching or probing of anal or genital cavities

ANSWERS:
10. a. The Fifth Amendment does not apply because the defendant was not compelled to prepare the
incriminating business records the government seized. Although he was compelled to turn them
over, the relevant time for determining whether a person has been compelled to incriminate
11. a. Neither protection applies. The questions asked were booking questions. The Fifth Amendment
does not apply to booking questions because they do not require an incriminating response.
12. A person cannot invoke the Fifth Amendment if he has already been tried for the crime to which
