MINNEAPOLIS: Police across the United States are using a variety of weapons on protesters during demonstrations against the death of an unarmed black man in police custody.
George Floyd died as a white Minneapolis police officer knelt on his neck for more than eight minutes, and his death has triggered a wave of protests across the country and around the world.
While many of the US events have been peaceful, some have turned violent, with scenes of arson, looting and clashes with police.
Police have used a range of weapons against peaceful protesters as well as members of the press during the demonstrations. Described as non-lethal, these weapons can seriously injure, disable and even kill.
Chemical irritants include tear gas and pepper spray, which cause sensations of burning, pain and inflammation of the airways.
Public health and infectious diseases experts have opposed the use of chemical irritants such as tear gas, saying in an online petition that they could increase risk for COVID-19 by “making the respiratory tract more susceptible to infection”.
Because chemical irritants can spread widely, bystanders and individuals other than the intended targets can be exposed to the chemicals.
Tear gas has been widely and frequently used by police to disperse protesters. CS or CN gas are chemical compound powders that spray from canisters. They produce a burning sensation in the eyes and mouth that incapacitates.
To protect themselves from pepper spray and other chemical irritants, protesters are dousing themselves with milk to help diffuse the burning sensations.
PEPPER SPRAY AND PEPPER BALLS:
Police have shot protesters with pepper spray both from handheld devices and projectiles. While pepper spray is chemically distinct from tear gas, it produces similar effects: burning and watering of the eyes and skin.
Police have also fired pepper balls, small projectiles containing chemical irritants. Such projectiles can contain PAVA spray, an irritant similar to pepper spray, as well as CS gas. The balls can be shot from launchers or modified paintball guns.
RUBBER, PLASTIC BULLETS:
Protesters have been hit by a variety of rubber, plastic, and “sponger” bullets. Reuters journalists in Minneapolis were shot by police with 40mm hard plastic projectiles during a protest in May.
Los Angeles Mayor Eric Garcetti said the city’s police department will minimise the use of rubber projectiles during peaceful protests going forward.
Kinetic impact projectiles include rubber, plastic, wooden, and “sponger” bullets, which are shot from launchers and guns.
A 2017 survey published by the British Medical Journal found that injuries from these caused death in 2.7 per cent of cases.
Protesters in Columbus, Ohio reported having been shot with wooden bullets by police forces.
Images online showed wooden dowel-shaped rods sliced into small, bullet-sized projectiles. The Columbus Police Department confirmed they used those devices against protesters on May 30 and said they are known as “knee knockers”.
STING BALL GRENADES:
Protesters have reported police using sting-ball grenades, which upon explosion, spray the surrounding area with rubber pellets. In addition to the rubber balls, the grenades can contain chemical agents or explode with bright light and sound.
Disorientation devices, commonly known as flashbangs or stun grenades, explode with bright light and sound in order to stun and disorient demonstrators. They can cause severe burns when fired at close range.
Constructed like a conventional grenade, the bright flash and the loud bang can cause temporary blindness, temporary loss of hearing and loss of balance. Parts of the device can burst and fly as shrapnel.
