Negative forensic evidence can be defined as the failure to find a trace after looking for it. Such evidence is often dismissed by referring to the aphorism "absence of evidence is not evidence of absence." However, this reasoning can be misleading in the context of forensic science. This commentary is designed to help forensic scientists understand the probative value of negative forensic evidence.
否定性法医证据可定义为在寻找后未能找到痕迹。此类证据常因引用“没有证据并非没有的证据”这一格言而被忽视。然而，在法医学背景下，这种推理可能会产生误导。本评论旨在帮助法医科学家理解否定性法医证据的证明价值。
