In this commentary, we point to similarities in characteristics of suspect and victim/witness statements and the underlying motivations of these individuals. Despite the similarities, there are differences in how such statements are evaluated by fact-finders and investigators. Retractions, for example, cast serious doubt on the credibility of victims/witnesses but appear not to diminish the power of confessions. Investigators need to recognize the wide range of motivations behind statements made to the authorities and be mindful of biased dispositions to doubt victims and believe confessors, especially when their statements are inconsistent or retracted. An investigative process that was entirely transparent would help ensure that inconsistencies and retractions, whether in statements from victims, witnesses, or suspects, are viewed in the context of other statements and eliciting circumstances.
在这篇评论中,我们指出了嫌疑人和受害者/证人陈述的特征以及这些人潜在动机之间的相似之处。尽管存在相似之处,但事实调查者和调查人员对这些陈述的评估方式却有所不同。例如,撤回陈述会严重怀疑受害者/证人的可信度,但似乎不会削弱供述的威力。调查人员需要认识到向当局陈述的陈述背后存在广泛的动机,并注意对受害者持怀疑态度而对供述者持信任态度的偏见倾向,尤其是当他们的陈述不一致或被撤回时。一个完全透明的调查过程将有助于确保无论是来自受害者、证人还是嫌疑人的陈述中的不一致和撤回,都能在其他陈述和引出陈述的环境背景下得到审查。
