Legal and Ethical Issues in Forensic Science

~5 min read 5 sections Ethics · Criminal Justice Ethics

Abstract

This paper examines key legal and ethical issues confronting forensic scientists, with a focus on three distinct problem areas: the falsification of evidence, misleading expert testimony, and improper conduct at crime scenes. Using the case of Massachusetts chemist Annie Dookhan—whose fabrication of thousands of drug test results led to wrongful convictions and widespread systemic harm—the paper illustrates how ethical failures can devastate the justice system. It also draws on the landmark Garrett and Neufeld study to show how invalid forensic testimony has contributed to wrongful convictions, and evaluates gaps in professional ethical codes governing crime scene conduct. The paper argues that forensic scientists must develop strong ethical reasoning skills to navigate situations where formal guidelines are absent or incomplete.

Key Takeaways

Introduction: Overview of forensic science ethics and fallibility
Falsifying Evidence: Dookhan case: fabricated drug tests, wrongful convictions
Ethics in Forensic Testimony: Invalid expert testimony and exonerations via DNA
Ethics at the Crime Scene: Crime scene evidence handling and code gaps
Conclusion: Forensic scientists must reason ethically beyond formal codes

What makes this paper effective

Uses a high-profile real-world case (Annie Dookhan) to ground abstract ethical principles in concrete, documented consequences, making the argument immediately credible.
Structures the analysis around three distinct ethical domains—evidence falsification, expert testimony, and crime scene conduct—giving the paper clear logical progression.
Acknowledges gaps in existing professional codes (e.g., the absence of crime scene guidelines from the American Academy of Forensic Sciences), showing critical engagement with institutional limitations.

Key academic technique demonstrated

The paper effectively combines case study analysis with reference to empirical research (the Garrett and Neufeld study in the Virginia Law Review) to support its claims. By citing both a publicized criminal case and a peer-reviewed legal study, the author demonstrates how to blend journalistic evidence with academic sources to build a well-rounded argument about professional ethics.

Structure breakdown

The paper opens with a general introduction to the fallibility of forensic evidence, then moves through three thematic sections—each addressing a separate ethical issue. The Dookhan case anchors the falsification section; published empirical findings anchor the testimony section; and professional code analysis anchors the crime scene section. The paper closes by emphasizing the forensic scientist's personal responsibility to reason ethically even when formal codes fall short.

Introduction

When most people think about the conviction of criminals, scientific evidence is considered among the most credible available. Scientific evidence is generally regarded as fail-safe by a majority of the public. However, this is not always the case. Many errors can occur during the accumulation of scientific evidence, and there are also cases in which evidence is purposefully altered to provide leverage for one party in a trial. There are additionally cases of negligence in which evidence was simply not handled to appropriate standards. Whatever the case may be, when people's lives are on the line, there are clear legal and ethical requirements for forensic scientists that must be upheld at all times. This analysis focuses on several examples of unethical or illegal behavior that have occurred in this profession.
