Limitations of artificial intelligence in forensic science

2023-09-29T23:28:45-05:00

The field of artificial intelligence in forensic science examines the prospects that exist today and in the future for integrating cutting-edge artificial intelligence (AI) technologies with traditional forensic and investigative procedures. But there are a number of restrictions attached to it. Let's take a quick look at the limitations of AI in toxicology and forensic medicine.

Machine training: For accurate interpretation, an AI machine needs a substantial data feed. For the machine to be able to learn from the data and be educated in several important areas of forensic medicine by forensic professionals, high-quality and quantity data is necessary so that the computer can interpret post-mortem examination results and provide a reliable opinion. Experts in forensic medicine must first manually annotate documents and photos with important discoveries, conclusions, and other information for computers. Forensic specialists must first put in a great deal of work to do this [1].

Trust: Experts in forensic medicine must establish confidence with their stakeholders and clients. They must demonstrate to the public the accuracy and reliability of their work. It will be quite concerning to see if the judges, the investigative body, and the general public will find the machine's opinion credible. The judiciary and the investigating agency are the clients of forensic experts, and they must be convinced by them that the conclusions drawn from AI are reliable and correct.

Medicolegal perspectives: Every piece of documented evidence must be presented orally by the expert witness in a court of law. Hence, the most crucial question in the realm of forensic medicine is whether the opinion generated by AI will be admitted as evidence in a court of law.

Infrastructure: To use AI, forensic medical professionals require the appropriate infrastructure and tools. Large data storage systems and high-performance computer infrastructure are examples of this. Every procedure will be quite expensive. Another major worry is whether less developed countries will be able to fund such arrangements.

Interoperability: It's possible that different AI tools can't communicate with one another. There may be instances where this results in the creation of data silos. There will be effort duplication as a result [2].

Ethical considerations: Artificial Intelligence is a potent tool that may increase precision and productivity. On the other hand, its application calls into question current regulatory frameworks and poses ethical issues. There are many who contend that the application of AI will hinder the custom of human judgment.

Lack of facilities: A significant portion of the populace lacks access to contemporary healthcare facilities. Therefore, legislators will have a very tough time creating high-tech infrastructure in the field of forensic medicine.

Human involvement: AI is merely an automated instrument. It cannot take the place of knowledge and human contact. Every piece of data that is input into the computer will need human labor. Therefore, forensic professionals will need to invest a great deal of time and effort in training the computer at first, and ongoing data updates are also required [3].

Forensic science, a multidisciplinary domain, employs a myriad of techniques to elucidate criminal investigations and legal disputes. Proteins, among the diverse array of biomolecules, have ascended as indispensable entities, playing a cardinal role in forensic applications. This review aims to offer an exhaustive overview of the importance and applications of proteins in forensic science, with an emphasis on their critical function as biomarkers and molecular tools. In the sphere of forensic identification, proteins have demonstrated their worth in determining the identity of individuals, both alive and deceased. The analysis of human DNA is one of the most renowned protein-based applications. Although DNA profiling is the gold standard, advancements in proteomics have ushered in supplementary methods such as protein profiling and peptide-based identification. These protein-centric techniques provide alternative avenues for forensic specialists, particularly when DNA samples are degraded or absent. Proteins have also been extensively utilized in crime scene analysis, where their presence can divulge crucial clues about the transpired events. Bodily fluids such as blood and saliva contain specific proteins that assist in identifying the offender or the victim. Moreover, the examination of gunshot residue, hair, and other trace evidence involves the detection of distinct protein markers, contributing to the reconstruction of the crime scene and enhancing the evidentiary value of the findings. Postmortem investigations have reaped substantial benefits from the incorporation of protein analysis techniques. The determination of the time of death, identification of the cause and manner of death, and differentiation between ante-mortem and postmortem injuries have been rendered more accurate through the study of protein degradation patterns and postmortem alterations. These insights are invaluable in delivering accurate testimonies and pivotal evidence in court proceedings. The emergence of advanced technologies, such as mass spectrometry and immunoassays, has broadened the scope of protein applications in forensic science. Mass spectrometry facilitates rapid and sensitive detection of proteins in minute quantities, proving particularly beneficial in the analysis of trace samples. Immunoassays leverage the specificity of antibodies to detect and quantify target proteins, enabling the identification of key biomarkers with high precision. In conclusion, proteins have surfaced as vital contributors in the realm of forensic science, offering a diverse array of applications in forensic identification, crime scene analysis, and postmortem investigations. The ongoing advancements in proteomics and related technologies promise to further augment the capabilities of these protein-centric approaches, ensuring their sustained utility in the quest for justice and truth.
