What are the potential limitations and biases associated with the use of e-fit descriptions in criminal investigations?
4 answers
The use of e-fit descriptions in criminal investigations, while a valuable tool, is not without its limitations and biases, which can significantly impact the outcome of an investigation. One of the primary concerns is the quality and accuracy of the descriptive information provided by eyewitnesses, which is crucial for generating e-fits. Research has shown that the Cognitive Interview (CI) technique can improve the accuracy and completeness of eyewitness recall, but the quality of descriptions, as judged by police officers, varies significantly, indicating a potential bias in how information is interpreted and utilized in creating e-fits. Moreover, the reliance on digital evidence, including e-fits, raises questions about the fairness of trials and the presumption of innocence. The improper and inconsistent use of technology, coupled with outdated procedural assurances, can compromise the impartiality of criminal investigations. This is further complicated by the challenges of abstracting criminal data from digital devices and wearable technology, which can be difficult to translate into concrete, legally admissible evidence. The increasing use of algorithms in law enforcement, aimed at making investigations more effective and efficient, introduces additional biases. These algorithms must be accurate, unbiased, and just, but the current regulatory frameworks are insufficient in addressing the complex interactions between system developers, users, oversight bodies, and profiled individuals, thus failing to fully guarantee algorithmic transparency and accountability. Furthermore, the digital age has expanded the scope of criminal investigations beyond national borders, necessitating access to electronic databases in several countries. This transnational collection of electronic data for criminal prosecution purposes inevitably encounters issues of personal rights and freedoms, requiring any restriction on the right to private life and data protection to be consistent with legality, necessity, and proportionality. In summary, while e-fit descriptions are a critical component of criminal investigations, their effectiveness is hindered by limitations and biases stemming from the quality of eyewitness descriptions, the use of digital and algorithmic evidence, and the challenges of ensuring fairness and protecting personal rights in a digital and globalized investigative context.
