The Independent Police Complaints Commissioner is investigating Dyfed-Powys police officers' actions leading up to the death of Mr Beynon, who is thought to have been suffering mental health problems. In October last year, an inquest jury found that the discharge of a Taser was the likely cause of a fireball which engulfed a suspect who officers were trying to detain in Plymouth.
But experts claimed it was most likely the spark from the stun gun which ignited the petrol. Police acknowledge that although Taser is described as a "less lethal" option, it is not without its risks. Those with underlying heart conditions can be particularly susceptible to suffering an adverse reaction to the stun gun.

Why has been a bad year for the Queen. More stories. 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 a baton or pistol or both, and non-lethal methods of subduing an attacker centered on hand-fighting techniques such as jujutsu and baton use. In the s and s 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 a one-on-one conflict. During the s and early s 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. Less-than-lethal weapons are also useful in keeping the peace in the aftermath of violent conflict.
Between the years of — after a three-year field study by the FBI's Firearm's Training Unit; In the use of Oleoresin Capsicum was first issued and used by the FBI as the first official law enforcement agency. In the late s and early s decade police began to adopt a new pepper spray delivery system based on the equipment used in paintballs. 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 higher pressure.
The impact of the capsule is immediately painful a pepperball's shell is thicker than a standard paintball and is fired at 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.
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, particularly with certain technologies interacting with appropriately vulnerable regions such as 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.
Some effects may be momentary while others may persist for some finite period of time. 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 s 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.
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. Taser XREP rounds are less lethal than conventional metal bullets, and are also propelled at lower speed by using less propellant.
More recently, high-velocity paintball guns are also used to launch less-lethal rounds, including the FN launcher and PepperBall commercial products. Fiocchi 12 Gauge rubber buckshot: containing 15, 8. M launcher ring airfoil projectile rounds. Hand grenades come in several less-lethal varieties, such as "flashbang" stun grenades , "sting" grenades with rubber shrapnel , and grenades designed to release chemical irritants described below. In stun grenades were used to capture the hijacked Sabena Flight , allowing the Israeli forces headed by Ehud Barak and including Benjamin Netanyahu to storm the plane and take it over within 10 minutes while capturing two terrorists and killing Ali Taha, the leader of the terrorist group and his aide, while rescuing all passengers three were wounded, and one died of her injuries several days later.
In June in Kenya, a stun grenade was used to draw attention, and then a real grenade along with an explosive package were used, killing many people. In April during the Kyrgyzstani uprising police attempted to use stun grenades to stop a demonstration but the crowd overwhelmed the police. In February stun grenades were seen used by Egyptian police against rioters.
Water cannons are commonly used in crowd and riot control, for dispersal or to prevent movement on a particular position. These water cannons are like pressure washers, but not quite as strong. Water-filled rounds for small arms are in experimental stages. Malodorants produce smells so horrible they cause people to leave the affected area. In , the Israeli Defence Forces began using Skunk for crowd control.
It is a form of mist sprayed from a water cannon, which leaves a terrible odor of rot or sewage on whatever it touches, and does not wash off easily. The active ingredient in pepper spray is oleoresin capsicum OC , an acrid irritant chemical derived from cayenne pepper plants. A estimate by the Internet Association of Chiefs of Police suggested at least 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 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. 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 Occupy Oakland protests. Often promoted for self-defense, mace is a spray of various formulations, that may include tear gas, pepper spray, and phenacyl chloride.
Psychochemical weapons are psychoactive drugs, such as BZ , LSD , Kolokol-1 , EA , and 3-Methylamphetamine designed to have a disorienting effect when used during combat or interrogation. During the 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 hostages were rescued, while died from exposure to the gas.
All the terrorists were ultimately killed by Russian forces through some combination of gas exposure and gunfire.
Blister agents , including CR gas , are less often used riot control agents. Sticky foam was tried by the U. Marine Corps in the peacekeeping Operation United Shield in with some success, but as a result various complications in its field use were also discovered.
Case in Point
Vehicle stoppers include a wide range of methods and devices meant to disable a vessel or vehicle to prevent attack by an oncoming vessel or vehicle or to stop that vessel or vehicle for evaluation. Vessel and vehicle stoppers may include kinetic, chemical, or electromagnetic means. Caltrops 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. Simple rows or clusters of sharpened sticks also known as punji sticks , and the use of small caltrops have been a feature of anti- infantry warfare for a long time. 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. Some South American urban guerrillas as the Tupamaros and Montoneros called them "miguelitos" and used these as a tactic to avoid pursuit after ambushes.
