ABSTRACT Do surveillance shots and phantom drawings of the perpetrator in child abuse cases, images that are widely published in public media, contaminate the identifications made by young victims? This question was raised in the later phases of the investigations into a Norwegian child abuse case that involved a large number of victims, where a suspect was apprehended, and a photo lineup with the victims was planned. The police sought to answer the question by conducting a simple experiment: Two samples of participants – children in the age range of the real victims but from a different part of the country, and police cadets – were presented with the published photographs and drawings of the suspect; after a short interval, they were asked to pick the man they had seen in a 12-person photo lineup that was planned to be used with the real victims. The results showed that media exposure – surveillance shots and phantom drawings – in this case did not increase the probability of selecting the suspect. It is concluded that criminal investigations in some cases may profit from research evaluations of police procedures and eyewitness performance, supporting the investigative process by sorting out unreliable procedures and increasing the quality of the evidence.

在刑事调查中招募目击者科学：Pocket Man案

摘要虐待儿童案件中肇事者的监视镜头和幻影图画，在公共媒体上广泛发布的图像，是否会污染年轻受害者的身份？在对涉及许多受害者的挪威儿童虐待案件进行调查的后期阶段，提出了这个问题，其中逮捕了一名犯罪嫌疑人，并计划与受害者合影。警察试图通过一个简单的实验来回答这个问题：参与者的两个样本-真正受害者的年龄范围内的孩子，但来自该国不同地区，以及警察学员-都收到了已出版的照片和图画。疑似; 在短暂的间隔之后，他们被要求挑选一个他们所见的人，该人计划以12人的照片阵容与真正的受害者一起使用。结果表明，在这种情况下，媒体曝光（监视镜头和幻影图）不会增加选择嫌疑犯的可能性。结论是，在某些情况下，刑事调查可能会从对警察程序和目击者表现的研究评估中受益，通过梳理不可靠的程序并提高证据质量来支持调查过程。
