Non-lethal weapons are designed to incapacitate or deter individuals without causing permanent injury or death. These weapons aim to minimize harm while achieving operational objectives, often used in law enforcement and military contexts to control situations with reduced risk of fatality.

Key research themes

1. How do legal frameworks regulate the use of non-lethal weapons in law enforcement versus armed conflict?

This research theme investigates the legal distinctions and regulatory mechanisms governing the deployment of non-lethal weapons, such as riot control agents and expanding bullets, especially their permitted use in law enforcement but explicit prohibition in armed hostilities. It highlights the intersections of international humanitarian law (IHL), customary international law, and human rights law as they relate to these weapons, addressing implications for legality, proportionality, and necessity. Understanding this dual regime is critical for policymakers and military and law enforcement agencies aiming to comply with international norms while managing civil unrest or conducting warfare.

Key finding: This paper elucidates that riot control agents and expanding bullets are uniquely authorized for law enforcement yet banned in warfare due to their differing physiological effects dependent on context and usage. It traces the... Read more
Key finding: This study differentiates the legal paradigms governing use of force in hostilities versus law enforcement, emphasizing that non-lethal weapons occupy a vital role in peace operations and asymmetric threat environments where... Read more

2. What are the implications and challenges of deploying non-lethal weapons for controlling civil dissent in liberal democracies?

This theme explores the socio-political and sensory effects of non-lethal weapons (NLWs) such as tear gas, sound cannons, rubber bullets, and skunk bombs during protests within democratic societies. It interrogates how these weapons function as instruments of sensory repression rather than solely as tools for physical incapacitation, affecting civil liberties, subordinate citizenship, and political expression. The research critically evaluates ethical concerns, human rights compliance, and the transformation of policing practices which may disincentivize dialogue and escalate state repression under the guise of crowd management.

Key finding: The article introduces the concept of 'Weapons of Sensory Repression' (WSRs), reframing non-lethal weapons as tools that operate by incapacitating specific human senses—visual, auditory, olfactory, proprioceptive—to... Read more
Key finding: This case study examines the excessive and indiscriminate use of rubber bullets and similar kinetic impact projectiles by Chilean police during mass protests, resulting in severe injuries including permanent blindness. It... Read more

3. What are the safety, injury profiles, and medical considerations associated with the use of non-lethal training ammunition and nonpowder firearms?

This research theme focuses on empirical investigations into the types and frequencies of injuries resulting from non-lethal projectiles used in training and civilian contexts, such as nonpowder firearms (air rifles, BB guns, pellet guns) and simulated training ammunition. It addresses risks to vulnerable populations, medical outcomes, and safety protocols needed to mitigate injury. Such studies inform regulatory perspectives, risk assessments, and improvements in protective equipment and training standards to minimize unintended harm during both operational training and civilian recreational use.

Key finding: Through case studies documenting superficial ballistic trauma from non-lethal training rounds impacting the head, this paper reveals patterns of acute soft tissue injury—initial swelling, bruising, and occasional bleeding... Read more
Key finding: Analyzing nationwide emergency room data over a decade, this study estimates approximately 55,060 head and neck injuries linked to nonpowder firearms (BB, pellet, air guns), predominantly affecting boys aged 6-12 years. The... Read more
