Fingerprint analysis plays a crucial role in forensic science, providing unique identification in criminal cases. Challenges include potential distortion at crime scenes and the risk of human error, as seen in the wrongful arrest of Brandon Mayfield. Psychological factors and emotional context can also influence expert judgments, necessitating measures to reduce bias and ensure the integrity of evidence in the judicial system.
