Evidence
2Discovery
- The informal and formal exchange

- Federal Rules of Civil Procedure (1938)
- state that every party in a civil action
- is entitled

privileged. - (Applicable in most states).
4Disclosure Rules - Criminal
- There is no general constitutional right
- to discovery in criminal cases.
- (Weatherford v. Bursey)

materiality of the evidence shall - be considered in its entirety.
- (Jencks v. U.S. Brady v. Maryland Kyles v.
Whitley)

11How Can Eyewitness TestimonyContribute to
Wrongful Convictions?
- At a trial, eyewitness testimony which
incriminates an offender is one of the most
influential pieces of evidence, - however,
- since DNA technology has developed, eyewitness
error is a - frequent cause of wrongful convictions.
- Psychological studies show that there is
extreme variation with false - identifications in both controlled field
studies and actual studies.
12How Important is Eyewitness Testimony in
Criminal Cases?
- The Police
- Crimes most likely to be cleared by arrest
- are those in which the offenders
- were captured within minutes
- or
- those in which an eyewitness provided
- a specific piece of information.
-
13Supreme Court Decisions
- Simmons v. U.S. (1968) Court recognized
dangers in the way police utilize lineups and
photo arrays. - United States v. Wade (1967) and Gilbert v.
California (1967) The Court held that a suspect
has the right to counsel during lineups (note
the suspect has no right to counsel during photo
arrays). - Stovall v. Denno (1967) and Neil v. Biggers
(1972) The Court acknowledges the danger of
suggestive procedures. - Neil v. Biggers (1972) and Manson v. Braithwaite
(1977) The Court articulated five minimal
factors which could increase the likelihood of an
accurate identification. Those factors were
opportunity, length of time, level of certainty,
degree of attention, the accuracy of the
witnesss prior description of the criminal. - Major issues no consideration of system
or estimator variables and the correlation
between accuracy and high confidence levels are
only somewhat more likely to be correct than
those who have a low confidence level.
14Exclusionary Rule
- The prosecutor is prohibited from
- using illegally obtained evidence
- during a trial.
- No personshall be compelled in any
- criminal case to be a witness
- against himself.
- (5th Amendment)
15Confession
- A confession by a defendant
- an admission of guilt
- is the most damaging evidence
- that can be presented
- at the defendants trial.
16Confessions
- Use of physical coercion to obtain
- confessions violates the due
- process clause of the 14th Amendment.
- (Brown v. Mississippi)
- Psychologically coerced confessions are not
voluntary and therefore not - admissible in court.
- (Ashcraft v. Tennessee)
17Interrogative Coercion Tactics That Are
Considered Illegal And Are Both Physical and
Psychological
- Physical force
- Abuse
- Torture
- Threats of harm or punishment
- Prolonged isolation
- Deprivation of food or sleep
- Promises of leniency
- Failure to notify the suspect of their Miranda
rights - Certain types of psychological influences
18Confessions
- A coerced confession does not
- automatically overturn a conviction.
- harmless error
- Arizona v. Fulminante (1991)
19Confessions
- the introduction of a confession makes the
other aspects of a trial in court superfluous,
and the real trial, for all practical purposes,
occurs when the confession is obtained. - (Justice William Brennan Colorado v. Connelly,
1986)
20The Supreme Court and Confessions
- The fundamental question asked by
- judges is whether the confession was voluntary.
- The U.S. Supreme Court has ruled
- that voluntariness of a confession
- is determined by the
- totality of circumstances.
- (Culombe v. Connecticut, 1961)
21Three Types of False Confessions
- Voluntary false confessions willful, without
elicitation. - Coerced-compliant confessions public admission
versus private knowledge of innocence. Example
Third-degree tactics. - Coerced-internalized confessions heightened
suggestibility truth and falsehood become
confused in the suspects mind.
22- Police can use trickery,
- and they can lie to suspects
- and otherwise mislead them.
- Allowable tactics
- Misrepresentation of the facts.
- Use of techniques that take unfair advantage of
emotions, beliefs, or medical condition of the
defendant. - Failure to inform the suspect of some important
fact or circumstance that might make the suspect
less likely to confess.
23Supreme Court and Trickery
- Frazier v. Cupp, (1969)
- Police misrepresentation, while relevant, is
insufficient to make a voluntary confession
inadmissible under a - totality of the circumstances analysis.
24Custodial Interrogation
- Miranda v. Arizona (1966)
- Chief Justice Earl Warren expressed
- concerns over the police-dominated
- atmosphere of interrogation rooms.
- Chief Justice Warren further held that warnings
were required to counteract the inherently
coercive nature - of stationhouse questioning.
25Miranda
- Miranda has become embedded in
- routine police practice to the point
- where the warnings have become
- part of our national culture.
- Chief Justice Rehnquist
- Dickerson v. U.S. (2000)
26Confession Questions
- Who has the burden to prove that
- a confession was not free and voluntary?
- How has the impact of Miranda changed under the
influence of - the Burger and Rehnquist courts?
27Search and Seizure

- secure in their person, houses,
- papers, and effects against
- unreasonable searches and seizures,
- shall not be violated.
- (4th amendment)
