As the United States continues to see widespread protests, images of unrest and accounts of violence against demonstrators have prompted outrage and more than a few questions.

Body armor. Rubber bullets. Pepper spray. What equipment do police officers need during a demonstration?

The list is long and the price tags can be astronomical. Heres a look at some of the equipment, how much they cost, and how they are supposed to be used.

Where does the money come from?

In some of the biggest US cities like New York City and Los Angeles, police department budgets make up a large portion of the cities budgets. Thats why there have been so many conversations recently about defunding police departments or otherwise redirecting money to other agencies in the community such as social services. A portion of this money goes toward the purchase and upkeep of equipment, as well as training needed to operate it properly.

The US government sometimes chips in too.

Recently, criticism has grown over a controversial arrangement called the 1033 Program, in which the US Department of Defense sends surplus military equipment to law enforcement agencies around the country. At least $760 million worth of equipment has been provided through the program since August 2017, according to a CNN analysis of federal data. That includes more than $5.3 million worth of gear like riot shields, gas masks, stun guns, specialized shotguns for shooting tear gas, and other items that could be used for riot control. During recent protests, police broadly have defended their tactics by pointing to sporadic looting, vandalism and projectiles thrown at them.

Private funds, grants and other programs also supply police departments with body cameras and defensive equipment such as body armor.

Because of this combination of local, federal and private funds, its not unusual to see a police force with several different models and brands of equipment in use at the same time.

The Arsenal

US police are authorized to use a variety of weapons, projectiles and other devices to control crowds or deploy during encounters with civilians. In general, they are called “less lethal” or “non-lethal” weapons. The Department of Defense says these weapons are designed to “enhance the commanders ability to deter, discourage, delay, or prevent hostile and threatening actions.”

The list below contains some of the most widely recognized and widely used “less lethal” weapons. Its important to note that, even in the best circumstances, such weapons are imperfect tools. “Were still in the blunderbuss age in less lethal weapons,” says Charles “Sid” Heal, a retired commander of the Los Angeles Sheriffs Department. Heal has taught less lethal force at military war colleges and is a former president of the California Association of Tactical Officers. “The options we have are still primitive. The standard is not perfection, its an alternative [to deadly force].”

Many of them are shrouded in official terminology, and the way the devices are referred to often varies from department to department. Heres a look at some commonly used devices.

Bean bag rounds / [hhmc]

Flexible baton rounds[hhmc]

What are they?The bean bag is a fabric pouch filled with small lead pellets, which is stuffed into a capsule and fired out of either a shotgun or a specialized weapon.

There is typically 40g (1.4oz) of lead pellets shot in each bean bag round.

Although they vary in size, compared to 9mm lead bullets, "less lethal" bullets are much larger.

This means they dont travel through air as fast.

However, both bean bag rounds and rubber bullets can travel long distances and still be lethal.

Charlie Mesloh, a professor in the Criminal Justice Department at Northern Michigan University, established a weapons lab at Florida Gulf Coast University in 2003, where he tested less lethal munitions. “We found that bean bags were much more accurate than other impact munitions, if you use them correctly," he says.

For bean bag rounds, Mesloh says, the ideal distance from which to shoot is usually about 10 feet.

How are police trained to use them?While there are no set rules of when to fire, officers are typically trained to only target advancing protesters who present a danger. And they are trained to target a specific person instead of firing into a crowd, which can increase the chances of more people getting hurt.

Training standards advise officers to aim KIPs at the lower abdomen or legs. "If you're going to miss, miss low," Heal says. Officers can also "skip" KIPs off the ground to lessen the likelihood of serious injury in close spaces.

Aiming from higher vantage points – such as from the roof of a building into crowds – makes it more likely that an individual will be struck in the head.

What are the health risks? In 2017, the British Medical Journal published a review that looked at reported deaths and injuries that KIPs caused when used in crowd control settings.

The report, which reviewed a 27-year period, identified 1,984 individuals who had been hit by various KIPs.

In those who survived, 71% of the injuries were classified as severe.

15% were permanently disabled.

3% died from their injuries.

84.2% of ocular injuries resulted in permanent blindness.

“I thought I died, I couldnt see and I couldnt breathe.”Josh Tuccio, protester, Atlanta

Josh Tuccio, 30, was taking part in a protest in Atlanta, Georgia, on May 28 when he said police began firing tear gas at demonstrators. “We werent even chanting at the time,” he told CNN. “We were just standing and walking.” In the confusion, Tuccio was shot four times with rubber bullets. One fractured his brow bone and his nose, and the others hit him in the throat and stomach.

After the panic subsided, Tuccio described the feeling as excruciating pain so widespread he couldnt even tell where hed been hit. He spent a night in the hospital, where he received several stitches and treatment for a scratched cornea (he was wearing eyeglasses at the time he was hit). Two weeks after the incident, he still had a welt the size of a golf ball on his throat. But the bruises on his body, he said, were finally starting to fade.

OC spray / [hhmc]

Chemical munitions[hhmc]

What is it?Oleoresin capsicum (OC) is an oil-based compound derived from a variety of pepper plants, including cayenne and chile. This compound is incorporated into a liquid to be used as an aerosol spray.

The purpose of pepper spray is to temporarily blind and incapacitate by causing a burning sensation in the eyes and irritation to the airway and skin.

Consider this: On the Scoville Scale, a scale used to rate the “hotness” of peppers,

A bell pepper rates at 0.

A jalapeño pepper rates at around 5,000.

A Carolina Reaper holds the record for being the hottest chili in the world rating at 1.5 million.

Most pepper sprays used by law enforcement rate at 500,000 to 2 million SHU though one brand rates at 5.3 million SHU, according to the Police Policy Studies Council.

The only higher-rating naturally occurring substances are pure Capsaicin and Resiniferatoxin, which are not commercially available.

How are police trained to use it? Pepper spray is designed to be sprayed at the face from a recommended distance of 3 feet (1m), according to The Police Policy Studies Council.

For crowd management situations, law enforcement offices purchase pepper spray in larger canisters of 470ml (16oz) up to to 1.4L (47oz).

Apart from a spray, it's also available as a foam or a gel which can be target-specific in high winds.

Officers are encouraged to expose themselves to OC during training, to understand how it feels and train the body if they experience secondary exposure.

What are the health risks?In recent years, some research has shown pepper spray has become less popular than other less lethal methods like stun guns. One reason is how damaging the compound can be.

Pepper spray is an inflammatory agent. It can cause severe irritation in the eyes as well as respiratory problems such as coughing and shortness of breath. Psychologically, the fear of blindness and suffocation can be overwhelming. Once the inflammation starts, the effects are difficult to neutralize.

The effects of pepper spray last, on average, 30 minutes. Mild conjunctivitis can persist for several hours.

CS gas[hhmc]

What is it?Some tear gas isnt really “gas,” but rather a powder that is pressurized into a compact tablet. A common tear gas compound, according to the Centers for Disease Control and Prevention, is chlorobenzylidenemalononitrile, or CS gas.

CS gas is named after Ben Corson and Roger Stoughton, the two American scientists who first synthesized the compound in 1928.

How are police trained to use it? Tear gas is outlawed for use in war under the 1925 Geneva Protocol. The United Nations Chemical Weapons Convention further expanded the definition to riot control agents — however, the US is one of the countries where riot control agents can still be used by law enforcement.

Officers typically deploy tear gas for purposes of crowd dispersal. There are different delivery methods for CS gas, according to the UN: Projectiles, canisters, grenades and sprays. Some canisters work by igniting a compound within, which releases the gas through holes.

Other tear gas devices contain multiple projectiles, or submunitions, that are released among the crowd.

“The first breath was fine. The next was like inhaling fire.”British journalist Michael Mosley, who was willingly exposed to CS gas while working on a documentary on chemical weapons development for BBC. BBC

What are the health risks?Tear gas has similar effects to pepper spray. It causes a burning sensation of mucous membranes, like in the eyes and throat. According to the CDC the effects include blurred vision, difficulty swallowing, a choking sensation, shortness of breath and chest tightness.

The indiscriminate dispersion makes it difficult to target individuals or small groups, particularly in windy conditions.

A 2017 systematic review of tear gas used for crowd control between 1990 and 2015 found that tear gas, dispersed in confined spaces, can cause permanent injury to the respiratory system and death.

What is it? A CED is a battery-operated, handheld device that sends pulses of electric current through a persons body via two small darts, almost like jumping a car. The dominant brand of CED is Taser.

Once fired, the darts attach to the skin and stay connected to the main device via copper wires that reach 25 feet (7.6m).

A single trigger discharges an electrical charge for 5 seconds. Most CED models are loaded with a single shot, though some advanced models can hold up to three shots.

The result is neuromuscular incapacitation – where the muscles contract uncontrollably, preventing the person from moving purposefully. This effect is also called "muscle tetanization."

CEDs are primarily used to incapacitate people at a distance. However, many CEDs also have a "drive-stun mode" which delivers an electric shock when pressed directly against a person resulting in localized, intense pain.

A Taser X26P, one model commonly used by law enforcement, can retail for about $1,200. Additionally, a single shot of a CED can cost about $20.

“…our research showed that it [CEDs] was used too often and I think thats a training and a supervision and an accountability issue.” Geoffrey P. Alpert, speaking in 2012 on the police use-of-force study sponsored by the National Institute of Justice

How are police trained to use it? Officers should give a verbal warning before using a CED, and are advised to avoid targeting the head, throat, around the heart and genitals. The preferred target area is the back because it has large muscle groups.

If the target is facing the CED, officers are advised to aim at the belt line, so that one dart attaches above the waist and one below the waist. This will cause most people to lose their balance and fall to the ground.

The more distance between where the two darts land on the body, the more nerve fibers are affected. 12 inches is optimal. Less than 4 inches typically creates a pain effect only.

Mesloh, the Northern Michigan University professor, notes that CEDs dont always work. They can miss their intended target or get caught on clothing.

What are the health risks? Common CED injuries are caused by the darts themselves depending on where they penetrate the body.

A paper released in 2020 by the UN High Commissioner for Human Rights says risk of significant injury or even death is increased in those with heart disease or those who have taken certain drugs.

How does it feel? "Its unpleasant," says Mesloh. "If youve ever been shocked, its similar. It's not that it's painful; it locks you up. You just really cant do a whole lot of anything."

Regulatory problems

When looking at less lethal weaponry, its important to note that there are no universal standards in equipment specifications or training.

“Its a totally unregulated field, and there is no oversight,” says Mesloh, the professor at Northern Michigan University. “All of the [product] information will be driven by the manufacturer, and the big ones may offer instructor training courses on things like less lethal munitions and diversionary devices. So what may happen is you go to a four or five-day school, you come back and you teach your entire department. But it may be a one-day class instead, and a lot of that information may be eliminated.”

In the United States, there is no federal regulatory body for law enforcement agencies, but professional associations like the International Association of Chiefs of Police, and non-governmental organizations like the Commission on Accreditation for Law Enforcement Agencies (CALEA) can provide important framework for law enforcement policy and practices. However, accreditation costs money to obtain and maintain, and participation in these programs is voluntary. Absent of compulsory standards, smaller departments will often model their policies off larger departments that have more resources to conduct research and training.

“In the United States, there are about 17,800 local law enforcement agencies and every single one is autonomous… They work for different communities and they have different expectations.” Former LASD commander Sid Heal

Although the US government has little authority to prescribe what local law enforcement agencies should do, the Department of Justice does have the authority to investigate unconstitutional policing practices. Historically, this has been a powerful way to regulate police misconduct. Former DOJ lawyers have noted however that the department has largely abandoned such investigations in recent years, and DOJ leadership has defended police and police tactics during the recent protests.

Personal protection

In addition to weaponry, police on the scene of protests will usually be clad in various types of protection, like body armor, helmets and shields. Its also not uncommon to see groups of officers with different types of protective equipment, because departments can rely on more than one type of funding to secure it. Private and federal grants can help departments secure and maintain protective equipment.

Smaller law enforcement agencies, or those without equipment needed to address a local crisis, can call on help from other agencies. This is called a mutual aid system, and such a request can even be routed through the Federal Emergency Management Agency or built into a state of emergency declaration.

“In these situations, youre expected to bring your own stuff,” says Heal, the retired commander with the Los Angeles Sheriffs Department.
