Bloodstains at crime scenes involving the use of a dangerous tool

Crimes involving dangerous tools - particularly knives - have long been a significant focus of law enforcement agencies, public opinion, the media, and criminal law doctrine. However, the Polish legal system lacks a unified legislative approach that would effectively regulate both the possession and use of knives in public spaces. Existing legal provisions remain scattered across the Code of Misdemeanors, the Penal Code, and the Act on Weapons and Ammunition, which creates challenges in both the application of the law and the effectiveness of preventive measures. The aim of this study is to provide an interdisciplinary analysis of knife-related crime in Poland, encompassing both criminal law and forensic perspectives. It includes an assessment of the effectiveness of current regulations and highlights the role of bloodstain pattern analysis (BPA) in reconstructing events. The research draws on legal acts, academic literature, statistical data from the National Police Headquarters, and training and certification practices of experts at both national and international levels. The findings indicate that a reductionist approach prevails in Poland, where blood traces are primarily treated as carriers of biological material for DNA analysis, while their reconstructive potential is largely overlooked.
