"Hired Guns": Establishing The Scope Of The Proper Cross-Examination And Argument Relating To Expert Witness' Compensation In Criminal Trials, Michael C. Kovac

Georgia Criminal Law Review

The outcomes of criminal cases can turn on the credibility of the parties’ expert witnesses. The compensation such experts receive in exchange for their work on cases can undermine their credibility, as it provides the experts with a financial incentive that might bias them in favor of the parties who retain them. While concerns with such bias have existed for decades, courts have been inconsistent in the defining the permissible scope of cross-examination and argument on the issue. Some courts have unduly curtailed such cross-examination and argument. Courts have also been inconsistent in their views of whether calling such expert …

Neuropsychological Malingering Determination: The Illusion Of Scientific Lie Detection, Chunlin Leonhard, Christoph Leonhard

Georgia Law Review

Humans believe that other humans lie, especially when stakes are high. Stakes can be very high in a courtroom, from substantial amounts of monetary damages in civil litigation to liberty or life in criminal cases. One of the most frequently disputed issues in U.S. courts is whether litigants are malingering when they allege physical or mental conditions for which they are seeking damages or which would allow them to avoid criminal punishment. Understandably, creating a scientific method to detect lies is very appealing to all persons engaged in lie detection. Neuropsychologists claim that they can use neuropsychological assessment tests (Malingering …

Mass Suppression: Aggregation And The Fourth Amendment, Nirej Sekhon

Georgia Law Review

The FourthAmendment's exclusionary rule requires that
criminal courts suppress evidence obtained as a result of
an unconstitutionalsearch or seizure. The Supreme Court
has repeatedly stated that suppression is purely
regulatory, not remedial. Its only purpose is to deter
future police misconduct, not to remedy past privacy or
liberty harms suffered by the defendant. Exclusion, in
other words, is for the benefit of community members who
might, sometime in the future, be subject to police
misconduct like that endured by the defendant.
Exclusion's regulatory purpose would be greatly aided if
criminal courts could identify when a suppression motion
involved Fourth Amendment …

The Wrong Decision At The Wrong Time: Utah V. Strieff In The Era Of Aggressive Policing, Julian A. Cook

Scholarly Works

On June 20, 2016, the United States Supreme Court held in Utah v. Strieff that evidence discovered incident to an unconstitutional arrest of an individual should not be suppressed given that the subsequent discovery of an outstanding warrant attenuated the taint from the unlawful detention. Approximately two weeks later the issue of aggressive policing was again thrust into the national spotlight when two African-American individuals — Alton Sterling and Philando Castile — were killed by policemen in Baton Rouge, Louisiana and Falcon Heights, Minnesota, respectively, under questionable circumstances. Though connected by proximity in time, this article will demonstrate that these …

Louisiana Rapper’S Case Speaks To Bigger Problems In The Criminal Justice System, Andrea L. Dennis, Erik Nelson, Michael Render

Popular Media

This article published on April 25, 2016 at the Huffington Post examines the case of McKinley Phipps. He was sentenced to thirty years of hard labor for a crime that, to this day, he insists he did not commit. During the trial prosecutors used Phipps’s rap persona and lyrics - remixed for special effect - to carefully construct a story of Phipps’s guilt. The article discusses how Phipps lyrics and persona contributed to his conviction and the progress of his appeals.

Schools Fail To Get It Right On Rap Music, Andrea L. Dennis

Popular Media

School officials treat rap music as a serious threat to the school environment. Fear and misunderstanding of, as well as bias against, this highly popular and lucrative musical art form negatively shape their perspectives on this vital aspect of youth culture.

As a result, students who express themselves through rap music in a way that challenges the schoolhouse setting risk the possibility of suspension, permanent exclusion and referral to the criminal justice system.

The ongoing case of Taylor Bell is the latest and most complex battleground on which this issue is playing out.

Applications Of Neuroscience In Criminal Law: Legal And Methodological Issues, John B. Meixner Jr.

Scholarly Works

The use of neuroscience in criminal law applications is an increasingly discussed topic among legal and psychological scholars. Over the past 5 years, several prominent federal criminal cases have referenced neuroscience studies and made admissibility determinations regarding neuroscience evidence. Despite this growth, the field is exceptionally young, and no one knows for sure how significant of a contribution neuroscience will make to criminal law. This article focuses on three major subfields: (1) neuroscience-based credibility assessment, which seeks to detect lies or knowledge associated with a crime; (2) application of neuroscience to aid in assessments of brain capacity for culpability, especially …

The Hidden Daubert Factor: How Judges Use Error Rates In Assessing Scientific Evidence, John B. Meixner Jr., Shari Seidman Diamond

Scholarly Works

In Daubert v. Merrell Dow Pharmaceuticals, the United States Supreme Court provided a framework under which trial judges must assess the evidentiary reliability of scientific evidence whose admissibility is challenged. One factor of the Daubert test, the “known or potential rate of error” of the expert’s method, has received considerably less scholarly attention than the other factors, and past empirical study has indicated that judges have a difficult time understanding the factor and use it less frequently in their analyses as compared to other factors. In this paper, we examine one possible interpretation of the “known or potential rate of …

The Degrading Character Rule In American Criminal Trials, Paul S. Milich

Georgia Law Review

The rule prohibiting evidence of the accused's bad
character is steadily degrading as courts and legislatures
expand existing exceptions and add new ones. In Georgia,

we saw the rule almost disappear as trial courts blithely
admitted a defendant's past crimes to prove his or her
"bent of mind" to commit the crime charged. This Article
examines why the character rule is losing ground.
The thesis is that a rule requiring as much careful
balancing as the character rule needs a clear, strong
justification to hold its own when faced with competing
claims to admit the evidence in the search for …

Toward Ethical Plea Bargaining, Erica J. Hashimoto

Scholarly Works

Defendants in criminal cases are overwhelmingly more likely to plead guilty than to go to trial. Presumably, at least a part of the reason that most of them do so is that it is in their interest to plead guilty, i.e., they will receive a more favorable outcome if they plead guilty than if they go to trial. The extent to which pleas reflect fair or rational compromises in practice, however, depends upon a variety of factors, including the amount of information each of the parties has about the case. Some level of informational symmetry therefore is critical to the …

Poetic (In)Justice? Rap Music Lyrics As Art, Life, And Criminal Evidence, Andrea L. Dennis

Scholarly Works

Courts routinely admit defendant-authored rap music lyrics as substantive evidence in the adjudication of criminal cases. In doing so, courts fail to recognize that rap music lyrics are art. Rather, judges view the interpretation of rap music lyrics as a subject of common knowledge, interpret the defendant's lyrics literally, and characterize lyrics as autobiographical depictions of actual events. In making admissibility decisions, courts must give consideration to the social constraints and artistic conventions impacting the composition and interpretation of rap music lyrics. More particularly, they must understand the commercialized nature of the rap music industry, artist claims of authenticity, and …

The Fourth Amendment Protection Against Unreasonable Searches And Seizures And The French Experience, Florence Sophie Boreil

LLM Theses and Essays

Under the American approach to criminal justice, freedom of the individual is of the utmost importance. The American criminal justice system reflects a distrust of abuse of power and an emphasis on protection of personal freedom. However, the French take a contrary approach; under French law, freedom is achieved through the State. This paper examines the protection of individuals’ rights in American and French criminal procedure. Focus will be given to tracking the police investigatory powers in each country through searches and seizures, and the impact that those powers have on individuals’ rights. This paper will assert that the police …

Should Michigan Rule Of Evidence 703 Be Revised?, Brian Benner, Ronald L. Carlson

Popular Media

Technical witnesses regularly assist the fact-finding process in Michigan trials. Jury or bench trials in federal and state courts routinely feature the appearance of experts. Properly policed by our courts, few forms of testimony hold more promise for advancing the truth-seeking function of American litigation. The expanding presence of experts raises hard questions. Are the Michigan rules in turn with modern needs? Should the state rule controlling the basis for expert opinion be aligned with the federal pattern? If Michigan Rule of Evidence 703 could stand revision, does proper alteration require significant additions not presently contained in either state or …

Balancing Government Efficienty And The Protection Of Individual Liberties: An Analysis Of The Conflit Between Executive Branch "Housekeeping" Regulations And Criminal Defendants' Rights To A Constitutionally Fair Trial, James F. Ponsoldt

Scholarly Works

This Article addresses the issue of whether an accused person should be entitled to obtain and use at trial relevant government information or the testimony of government employees to prove his innocence, regardless of whether he has revealed in advance to his adversary his intended use of that information or the specific content of that testimony. Part I describes the federal "housekeeping" statute and the Justice Department's housekeeping regulations, which require that subpoenaed government employees not disclose evidence unless the person seeking that evidence has first summarized the requested evidence in advance, explained its intended use, and obtained permission from …

"A Most Deplorable Paradox": Admitting Illegally Obtained Evidence In Georgia--Past, Present, And Future, Donald E. Wilkes Jr.

Scholarly Works

This Article explores the admissibility of illegally obtained evidence in Georgia criminal cases prior to 1961 and during the post-Mapp era and endeavors to assess the future admissibility of illegally seized evidence in Georgia under both federal and state law.

Claiming Illegal Electronic Surveillance: An Examination Of 18 U.S.C. 3504(A)(1), Margaret V. Sachs

Scholarly Works

This Comment will first discuss the making of claims under section 3504(a)(1), and will show that the statute should not be read to require that claims be accompanied by evidentiary support. It will then suggest that the statute should be read to encompass claims of attorney-third party conversations. Finally, the scope of the government's response to section 3504(a)(I) claims will be examined.

A Critique Of Two Arguments Against The Exclusionary Rule: The Historical Error And The Comparative Myth, Donald E. Wilkes Jr.

Scholarly Works

“The great body of the law of evidence consists of rules that operate to exclude relevant evidence.” The most controversial of these rules are those which prevent the admission of probative evidence because of the irregular manner in which the evidence was obtained. Depending on whether the method of obtaining violated a provision of positive law, irregularly obtained evidence may be separated into two classes. Evidence obtained by methods which meet legal requirements but contravene some moral or ethical principle is unfairly obtained evidence. Evidence obtained in violation of a legal right or immunity is improperly obtained evidence, regardless of …

False Or Suppressed Evidence: Why A Need For The Prosecutorial Tie?, Ronald L. Carlson

Scholarly Works

Many United States Supreme Court decisions have overturned criminal convictions for the reason that the government employed false evidence to obtain the conviction or failed to disclose relevant evidence important to the defense. In reversing federal or state judgments, the Court often has located direct proof of wrongdoing by the prosecutor. The notorious “bloody shorts” case is an example in point. There, the state introduced as evidence a pair of men’s “blood-stained” undershorts to achieve conviction of the accused. When the blood turned out to be red paint, the Supreme Court granted habeas corpus relief to the defendant because “[ilt …
