To illustrate this point, Liao Che-hsien mentions a case in the Taipei suburb of Chungho in which a robber left fingerprints behind on the victim's motorcycle helmet. When the evidence was presented, however, the suspect claimed that he lived near the victim and must have accidentally brushed his hand across the helmet. Because there was no other evidence to support the fingerprints, the suspect could not be proven guilty.
廖哲賢舉例，過去中和有件強盜案，在受害的機車安全帽上採到可能是嫌疑犯的指紋，但涉嫌人辯稱是住在附近，不經意地碰到機車，因為缺乏指紋之外的旁證，而無法將他繩之於法。
