charges, or fire live ammunition at crowds. In the late 1980s and early 1990s, the Non-lethality Policy Review Group at U.S. Global Strategy Council in Washington and other independent think tanks around the world called for a concerted effort to develop weapons that were more life-conserving, environmentally friendly, and fiscally responsible than weapons available at that time. The U.S. Congress and other governments agreed and began an organized development of non-lethal weapons to provide a range of options between talking and shooting. Recognizing the need to limit the escalation of force, research and development of a range of non-lethal weapons has since been undertaken internationally by governments and weapons manufacturers to fill the need for such weapons. Some non-lethal weapons may provide more effective riot control than firearms, truncheons or bayonets with less risk of loss of life or serious injury. Before the general availability of early military non-lethal weapons in the mid 1990s, war-fighters had few or no casualty-limiting options for the employment of scalable force and were continually at risk whenever lethal force was prohibited during sensitive missions. In 2001, the United States Marine Corps revealed its development of a less-than-lethal energy weapon called the Active Denial System, a focused high frequency microwave device said to be capable of heating all living matter in the target area rapidly and continuously for the duration of the beam, causing transient intolerable

but no lasting damage. The skin temperature of a person subjected to this weapon can jump to approximately in as little as 2 seconds depending on the skin's starting temperature. The system is nonlethal (the penetration of the beam into human skin is only a few millimeters). In 2004, author Jon Ronson cited an unclassified military report titled "Non-Lethal Weapons: Terms and References" 21 acoustic weapons were listed, in various stages of development, including the Infrasound ("Very low-frequency sound which can travel long distances and easily penetrate most buildings and vehicles ... biophysical effects are projected to be: nausea, loss of bowels, disorientation, vomiting, potential internal organ damage or death may occur. Superior to ultrasound...)", however no such effects had been achieved . In 2010, the ''Joint Non-Lethal Weapons Directorate Non-Lethal Weapons Reference Book'' was created. The weapons in this book are currently in development.


Police

Until the development of non-lethal weapons, police officers around the world had few if any non-lethal options for riot control. Common tactics used by police that were intended to be non-lethal or less lethal included a slowly advancing wall of men with batons, officers on horses trained to deal with policing situations, or a charge into a riot using the flats of sabers. Other reasonably successful approaches included shotguns with lower-powered cartridges, "salt shells", using bean-bag rounds and ricocheting shots off of the ground. In the mid-20th century, with the integration of fire-control systems into major cities, police found that high-pressure fire hoses could be effective in dispersing a crowd (the use of water cannons and fire trucks has remained an effective non-lethal tactic to disperse riots). Trained police dogs were also commonly used to scare and disperse rioters and apprehend individuals. In the 1980s the development of high-tensile plastics like Kevlar and Lexan revolutionized personal armor and shields, and led to new tactics for riot squads and other special-purpose teams. Officers could now stand up against violent rioters throwing dangerous projectiles without having to resort to lethal methods to quickly disperse the danger. Coupled with the introduction of effective non-lethal chemical agents such as tear gas and offensive-odor canisters, and non-lethal impact rounds such as rubber bullets and "bean bag" flexible baton rounds, riot tactics were modified to rely less on violent response to attacking rioters than on a return to the slowly advancing wall, with supporting officers firing non-lethal ordnance into the crowd to discourage advance. Police officers on patrol were traditionally armed with batons or pistols or both, and non-lethal methods of subduing an attacker centered on hand-fighting techniques such as jujutsu and baton use. In the 1980s and 1990s officers began deploying non-lethal personal sidearms such as pepper sprays, and eventually electroshock weapons such as tasers, which were developed for use by police and also found a market in self-defense by private citizens. However, these weapons were developed for non-lethal resolution of one-on-one conflicts. During the 1990s and early 2000s (decade), interest in various other forms of less-than-lethal weapons for military and police use rose. Amongst other factors, the use of less-than-lethal weapons may be legal under international law and treaty in situations where weapons such as aerosol sprays or gases defined as chemical are not. Between the years of 1987–1990, after a three-year field study by the FBI's Firearms Training Unit; In 1990, the use of oleoresin capsicum was approved and used by the FBI, the first official law enforcement agency to do so. In the late 1990s and early 2000s (decade), police began to adopt a new pepper spray delivery system based on the equipment used in paintball. A specialized paintball, called a "pepperball", is filled with liquid or powdered capsaicin, the active ingredient in pepper spray, and is propelled by compressed gas using a paintball marker similar to those used for the sport but operating at a higher pressure. The impact of the capsule is immediately painful (a pepperball's shell is thicker than a standard paintball and is fired at a higher velocity), and it breaks open on impact, dispersing the capsaicin with similar effect to aerosol-delivered pepper spray. However, to be most effective, pepper spray must contact the eyes, nose, or mouth of the target; pepper spray on clothing or tougher skin has a much reduced effect.

Effects

Non-lethal weapons have a design intent to provide an effect to reliably elicit a degree of incapacitation but without the typically lethal or permanent lasting effects of conventional weapons. This design intent has often made them a weapon of choice for use by law enforcement during civil protests, etc. Effect modalities vary by the technology being employed: kinetic projectiles function by blunt impact which actuate pain receptors to elicit a behavioral change, lights affect visual perception, acoustics affect hearing, etc. Notwithstanding their design intent, non-lethal weapons can still cause harm. This is particularly true with certain technologies that interact with appropriately vulnerable regions; an example is kinetic munitions on the head, neck, eyes, abdominal and urogenital regions of the body. As a result, some analysts describe "non-lethal" as a misnomer and recommend defining them as "less-lethal", whereas other sources identify "non-lethal" as representing a goal of minimization of producing fatalities or permanent injuries while not literally requiring minimization to a zero probability thereof. Because the design intent is to avoid/minimize permanence, the effects invariably have been transient in nature. Some effects may be momentary while others may persist for some finite period of time.


Mechanics

Non-lethal weapons are intended to minimize injury or death. While people are occasionally seriously injured or killed by these weapons, fatalities are relatively infrequent. Causes of death from non-lethal weapons are varied and occasionally uncertain. Misplaced or ricocheting shots, pre-existing medical conditions, inadequate user training, repetitive applications and intentional misuse have been implicated in different cases where death has occurred. As different parts of the body differ in vulnerability, and because people vary in weight and fitness, any weapon powerful enough to incapacitate may be capable of killing under certain circumstances. Thus, "non-lethal force" does have some risk of causing death: in this context, "non-lethal" means only "not ''intended'' to kill". Several groups maintain there is great room for improvement in non-lethal weapons and procedures for their use. Claims for the relative safety of such weapons are usually contingent on their being used "properly". For example, the rubber bullets developed during the 1960s were supposed to be fired at the ground and hit the target only after ricochet, and other non-lethal bullets are designed to be fired at the lower body; they can be lethal if fired directly at the head.


Ammunition

Non-lethal rounds are firearm rounds which are designed to incapacitate, but not kill, a target. The rounds rely on the transfer of kinetic energy and blunt force trauma to accomplish this incapacitation. Rubber bullets, rubber buckshot, soft polymer rounds, wax bullets, plastic bullets, beanbag rounds, sponge grenades, ring airfoil projectiles (both kinetic and tear gas projectiles) and rubber bullets with electroshock effect (e.g. Taser XREP rounds) are less lethal than conventional metal bullets, and are also propelled at lower speed by using less propellant. "Bean bag" type bullets are sometimes referred to as flexible baton rounds. More recently, high-velocity

s are also used to launch less-lethal rounds, including the FN 303 launcher and PepperBall commercial products. There is also the Variable Velocity Weapon Concept, for which a propulsion energy source may not yet have been clearly established and/or finalized. In any case, all of these technologies apply the same basic mechanism, which is to launch a mass at the target that interacts kinetically.

Gases and sprays


Water

Water cannons are commonly used in crowd and riot control, for dispersal or to prevent movement on a particular position. These water cannons are intended to disperse crowds with little risk of harm, but the pressure can still cause eye injuries or even death. Water-filled rounds for small arms are in experimental stages. Electrified water cannons were in development but was abandoned.

suggested at least 113 pepper spray-related fatalities had occurred in the United States, all with aggravating factors such as intoxication, pre-existing health problems, or from the police use of airway-restrictive immobilizing holds that can cause positional asphyxia. The Southern California chapter of the American Civil Liberties Union recommends against maximal prone restraint techniques following pepper spray application, and they caution that anyone sprayed should be monitored to ensure effective breathing.


Tear gas

The use of chemical weapons such as tear gas ( CS) and pepper spray ( OC) has come under increasing scrutiny and criticism due to studies showing serious long term side effects. Many police forces are no longer exposing their members to the chemicals during training. Journalist Rubén Salazar was killed in Los Angeles in 1970 by an errant CS gas canister during the Chicano riots. Other serious injuries and fatalities have occurred from either tear gas itself or the projectiles it is delivered in, including the critical injury of veteran Scott Olsen from a tear gas canister during the 2011 Occupy Oakland protests.

Sleep gas

During the 2002 Moscow theater hostage crisis, Russian special forces used an unidentified gas (thought to be 3-methylfentanyl or another fentanyl variant dissolved in halothane gas) in an attempt to induce sleep in both hostages and terrorists. Many of the hostages and terrorists (including all of the suicide bombers) were anesthetized, but some terrorists donned gas masks and thus were able to avoid the effects of the gas. Because the agent used was a potent Fentanyl derivative (a synthetic opioid), it causes respiratory depression and ultimately respiratory failure if administered in high enough dosages. The central nervous system effects, such as anesthesia and respiratory depression could have been reversed by an opioid antagonist such as naloxone, which is stocked by hospitals and most ambulances. However, because the Russian authorities did not release any information regarding what type of agent was used, medical professionals were unaware that an opioid had been used during the rescue attempt and thus were unable to administer the antidote which could have saved most hostages. Approximately 700 hostages were rescued, while 130 died from exposure to the gas. All the terrorists were ultimately killed by Russian forces through some combination of gas exposure and gunfire.

They are known to have been in use since Roman times and may have been used earlier: the concept was familiar to the 4th century BC Greeks, who used rocks, brush, nets and trees placed in the path of enemy conveyances on land or ensnarement devices hidden under water to achieve the same result: stop the enemy or suspected hostile in his tracks for examination or to prevent or limit incursions. Contemporary caltrops look something like large jacks from the childhood game. Placed in the path of oncoming wheeled or tracked vehicles, they are meant to foul wheels, destroy tires and tracks, and incapacitate vehicles. However, due to the difficulty of mass-producing them in the pre-modern age, they were rarely used except in the defense of limited areas or chokepoints, especially during sieges, where they were used to help seal breaches. Increasing ease of production still did not prevent these methods from slowly falling out of favor from the late Middle Ages onward. Caltrops are still sometimes used in modern conflicts, such as during the Korean War, where Chinese troops, often wearing only light shoes, were particularly vulnerable. In modern times, special caltrops are also sometimes used against wheeled vehicles with pneumatic tires. Some South American urban guerrillas as the

Riot gun

In current usage a riot gun or less-lethal launcher is a type of firearm that is used to fire "non-lethal" or "less-lethal" ammunition for the purpose of suppressing riots. Less-lethal launchers may be special purpose firearms designed for riot control use, or standard firearms, usually shotguns and grenade launchers, adapted to riot control use with appropriate ammunition. The ammunition is most commonly found in 12 gauge (.729 inches) shotguns and 37mm and 40 mm (1.46 and 1.57 inches) grenade launchers. In the United States, the term riot gun more commonly refers to a riot shotgun.


Electroshock weapons

Electroshock weapons are incapacitant weapons used for subduing a person by administering electric shock aimed at disrupting superficial muscle functions. One type is a conductive energy device (CED), an electroshock gun popularly known by the brand name " Taser", which fires projectiles that administer the shock through a thin, flexible wire. Other electroshock weapons such as stun guns, stun batons, and electroshock belts administer an electric shock by direct contact.


Directed energy weapons

Directed energy weapons are weapons that emit energy in an aimed direction without the means of a projectile. They are non-lethal and can immobilize people as well as machines (e.g. vehicles). Directed energy weapons include electromagnetic weapons, (including laser weapons) and microwave weapons, particle beam weapons, sonic weapons and plasma weapons.

The pulsed energy projectile is intended for riot control and is said to work over distances of up to 2 km. It weighs about 230 kg and will probably be mounted on vehicles. The weight could become lighter as laser production technology improves. The system was developed by Mission Research Corporation (now owned by Orbital ATK). It uses a chemical

United States Special Operations Command FY 2010 plans included starting developmental work on a counter UAV pulsed energy projectile.

s. The emitters are usually lasers, making what is termed a ''laser dazzler''. Most of the contemporary systems are man-portable, and operate in either the red (a laser diode) or green (a diode-pumped solid-state laser, DPSS) areas of the electromagnetic spectrum. Initially developed for military use, non-military products are becoming available for use in law enforcement and security.

. The dazzler is a non-lethal weapon intended to cause temporary blindness or disorientation and therefore falls outside this protocol. The personnel halting and stimulation response rifle (PHASR) is a prototype non-lethal laser dazzler developed by the Air Force Research Laboratory's Directed Energy Directorate, U.S. Department of Defense. Its purpose is to temporarily disorient and blind a target. Blinding laser weapons have been tested in the past, but were banned under the 1995 UN

to send messages and warning tones over longer distances or at higher volume than normal loudspeakers. LRAD systems are used for long-range communications in a variety of applications including as a means of non-lethal, non-kinetic crowd control. Though they have been called "sonic weapons", LRADs are not inherently for military use. The round black devices on top of New York City police Hummers are LRADs. According to the manufacturer's specifications, the systems weigh from and can emit sound in a 30°- 60° beam at 2.5 kHz. The manufacturer also produces systems for public address and mass notification use that broadcast 360°.


Safety and legal status

In the United States, the University of Texas-Austin Institute for Advanced Technology (IAT) conducts basic research to advance electrodynamics and hypervelocity physics related to electromagnetic weapons. Although generally considered "non-lethal weapons", electromagnetic weapons do pose health threats to humans. In fact, "non-lethal weapons can sometimes be deadly." United States Department of Defense policy explicitly states that non-lethal weapons "shall not be required to have a zero probability of producing fatalities or permanent injuries." Although a Human Effects Advisory Panel was established in 1998 to provide independent assessment on human effects, data, and models for the use of 'non-lethal weapons' on the general population, the TECOM Technology Symposium in 1997 concluded on non-lethal weapons: "Determining the target effects on personnel is the greatest challenge to the testing community," primarily because "the potential of injury and death severely limits human tests." However, "

Terrorism concerns

Loren Thompson, chief operating officer of the Lexington Institute in Virginia states that: "The relevant (electromagnetic weapon) technology is well within the grasp of some countries and transnational terrorist groups", and further states that U.S. hardware is susceptible to microwave and other directed-energy weapons. Suitable materials and tools to create electromagnetic weapons are commonly available. "The threat of
