Audiovisual evidence can provide several benefits to the justice system. They can facilitate the recording of court hearings and enrich the evidence by portraying a privileged version of the facts that occurred. Nevertheless, their interpretation may be influenced by some biases that have been studied by the cognitive sciences, such as camera perspective bias, body-worn perspective bias and slow motion bias. In this paper, we analyze the impacts of these biases on the justice system, focusing in the procedural law. The existence of such biases requires prudence in the valuation of audiovisual evidence, including to mitigate its evidential value. Based on a critical and systematic review of the literature in the area, some suggestions are proposed to minimize the harmful effects of these biases in the variation of audiovisual evidence, providing the inicial parameters of a reflexion to be extended.
