Questions & Answers

Q: Why is eyewitness testimony a significant factor in wrongful convictions?

Eyewitness testimony is often relied on in court cases, but research shows it can be unreliable due to memory errors and suggestibility, leading to false identifications and convictions.

Q: What reforms have been suggested to improve the reliability of eyewitness identifications?

Reforms include providing warnings to witnesses before lineup or photo array viewings, using double-blind administrators to prevent bias, and avoiding confirming feedback to ensure accurate identifications.

Q: What did the National Academy of Science report recommend regarding forensic evidence?

The report highlighted DNA testing as the only validated forensic discipline and emphasized the need for validation in pattern evidence disciplines like fingerprints and tire tracks to prevent misleading conclusions in court.

Q: Why is it crucial for forensic evidence, like fingerprints, to be validated scientifically?

Validating forensic evidence ensures accuracy in identifying individuals and linking evidence to specific sources, preventing wrongful convictions based on subjective interpretations rather than objective scientific analysis.

Summary & Key Takeaways

• Eyewitness testimony is a major cause of wrongful convictions.

• Research has shown specific techniques for accurate identifications.
