本文从一盗窃案件中存在错误的指印鉴定说起,由正反两方面揭示指纹鉴定本身的积极作用及存在的问题。在绝大部分案件中,指纹鉴定作为唯一定罪证据是可行的,但基于对冤假错案的防范而采用“暂时”不采信指纹鉴定作为盗窃案孤证的意见。 This article starts with the identification of the wrong fingerprints in a theft case, and reveals the positive functions and existing problems of fingerprinting by both positive and negative aspects.
