Marking cartridges are an increasingly popular form of nonlethal training munitions used primarily for military live-fire simulations. We report a case of ocular trauma due to such a projectile, resulting in the complete loss of vision and placement of a scleral shell. A 20-year-old man presented with decreased visual acuity in his right eye after being struck at close range by a marking cartridge during military training. Computed tomography imaging revealed a retained metallic foreign body within a deflated right globe, prompting emergent exploration and repair of the right globe. Postoperative course was complicated by pain and pruritis which resolved over a period of months. Nonlethal weapons, such as marking cartridges, are increasingly used for civilian crowd control as well as military and law enforcement training. Despite guidelines mandating the use of personal protective equipment with marking cartridges, eye protection may not be consistently used during simulated combat exercises. To the best of our knowledge, this is the first formal report of ocular injury due to this type of ammunition. Based on this case, we discuss other similar types of nonlethal munition used by military and law enforcement, their risks to the eye and orbit, and what steps may be undertaken to reduce future injury.

Since the release of the first 3D-printed firearm, "The Liberator," the occurrence of 3D-printed firearms in criminal activities has increased, highlighting the need for forensic research on these weapons. This study presents a technical examination of a 3D-printed firearm received by the National Institute of Criminalistics and Criminology (NICC), focusing on its design, ballistic performance, and its potential for microscopic comparative analysis. The firearm, resembling a 3D-printed pistol Yeet22, is primarily constructed from polymer parts, with the exception of the firing pin, barrel, and various springs and screws.

Introduction: China enacted an excise tax on e-cigarettes in November 2022, which offers a distinctive opportunity to examine the industry's reactions to this fiscal adjustment. This study delves into the industry's pricing strategies following the introduction of the excise tax, facilitating a thorough assessment of the subsequent impact on market dynamics and the government's revenue streams.
Methods: We developed a TaXSiM model specifically tailored for e-cigarettes in China by integrating the country's e-cigarette tax framework.
Automated interpretation of comparison scores for firearm toolmarks on cartridge case primers.

An automated approach for evaluating the strength of the evidence of firearm toolmark comparison results is presented for a common source scenario. First, comparison scores are derived describing the similarity of marks typically encountered on the primer of fired cartridge cases: aperture shear striations as well as breechface and firing pin impressions. Subsequently, these scores are interpreted using reference distributions of comparison scores obtained for representative known matching (KM) and known non-matching (KNM) ballistic samples in a common source, score-based likelihood ratio (LR) system.

Background: A novel method for trapping voles is the use of pistol-like explosive tools loaded with bolt-action ammunition. When triggered the vole is killed by the very high gas pressure created. Accidental releases can result in facial and/or eye injuries.

Crimes, such as robbery and murder, often involve firearms. In order to assist with the investigation into the crime, firearm examiners are asked to determine whether cartridge cases found at a crime scene had been fired from a suspect's firearm. This examination is based on a comparison of the marks left on the surfaces of cartridge cases.
