Riot Control
Riot control is a form of public order policing used by law enforcement, military, paramilitary or security forces to social control, control, disperse, and arrest people who are involved in a riot, unlawful Demonstration (people), demonstration or unlawful protest. If a riot is spontaneous, then actions which cause people to stop and think (e.g. loud noises or issuing instructions in a calm tone) can be enough to stop it. However, these methods usually fail when there is severe anger, or the riot was planned or organized. Riot control personnel have long used less lethal weapons such as Baton (law enforcement), batons and whips to disperse crowds and detain rioters. Since the 1980s, riot control officers have also used tear gas, pepper spray, rubber bullets, stun grenades, and electric tasers. In some cases, riot squads may also use Long Range Acoustic Devices, water cannons, armoured fighting vehicles, aerial surveillance, police dogs or mounted police on horses. Persons perform ...

Taser
Taser (stylized in all caps) is a line of handheld conducted energy devices (CED) sold by Axon Enterprise (formerly Taser International). The device fires two small barbed darts intended to puncture the skin and remain attached to the target until removed by the user of the device. The darts are connected to the main unit by thin wires that achieve a high dielectric strength and durability given the extremely high-voltage electric current they conduct (typically 50,000 volts, or 2,000 volts under load), which can be delivered in short-duration pulses from a core of copper wire in the main unit. This enormous rush of current into the body produces effects ranging from localized pain to strong involuntary long muscle contractions, causing " neuromuscular incapacitation" (NMI), based on the mode of use (tasing frequency and environmental factors) and connectivity of the darts. When successfully used, the target is said to have been " tased". The first Taser conducted energy we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston Massacre
The Boston Massacre, known in Great Britain as the Incident on King Street, was a confrontation, on March 5, 1770, during the American Revolution in Boston in what was then the colonial-era Province of Massachusetts Bay. In the confrontation, nine British soldiers shot several in a crowd, estimated between 300 and 400, who were harassing them verbally and throwing various projectiles. The event was subsequently described as "a massacre" by Samuel Adams, Paul Revere, and other leading Patriots who later became central proponents of independence during the American Revolution and Revolutionary War. British troops had been stationed in the Province of Massachusetts Bay since 1768 in order to support Crown-appointed officials and to enforce unpopular legislation implemented by the British Parliament. Amid tense relations between the civilians and the soldiers, a mob formed around a British sentry and verbally abused him. He was eventually supported by seven additional s ...

Nika Riots
The Nika riots (), Nika revolt or Nika sedition took place against Byzantine emperor Justinian I in Constantinople over the course of a week in 532 AD. They are often regarded as the most violent riots in the city's history, with nearly half of Constantinople being burned or destroyed and tens of thousands of people killed. Background The Roman Empire had well-developed associations, known as '' demes'', which supported the different factions (or teams) to which competitors in certain sporting events belonged, especially in chariot racing. There were initially four major factions in chariot racing, differentiated by the colour of the uniform in which they competed; the colours were also worn by their supporters. These were the Blues (''Veneti''), the Greens (''Prasini''), the Reds (''Russati''), and the Whites (''Albati''), although by the 6th century the only teams with any influence were the Blues and Greens. Emperor Justinian I was a supporter of the Blues, although his sup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
April 9 Tragedy
April 9 Tragedy (also known as the massacre of Tbilisi or Tbilisi tragedy) refers to the events in Tbilisi, Georgian Soviet Socialist Republic, on April 9, 1989, when an anti-Soviet, pro-independence demonstration was crushed by the Soviet Army, resulting in 21 deaths and hundreds of injuries. April 9 is now remembered as the National Unity Day ( ka, ეროვნული ერთიანობის დღე, tr), an annual public holiday. Prelude In the Georgian SSR, the anti-Soviet movement grew more active in 1988. Political groups opposed to the Soviet Union organized a number of protests and gatherings in Tbilisi. The conflict between the Soviet government and Georgian nationalists deepened after the so-called Lykhny Assembly on March 18, 1989, when several thousand Abkhaz demanded secession from Georgia and restoration of the Union republic status of 1921–1931. In response, the anti-Soviet groups organized a series of unsanctioned meetings across the repub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riot Shield
A riot shield is a lightweight protection device, typically deployed by riot police and some military unit during protest, though also utilized by protestors. Riot shields are typically long enough to cover an average-sized person from the top of the head to the knees, though smaller one-handed models may also be used. They are generally intended to be used in riot control, to protect the user from melee attacks with blunt or edged weapons and also Stone throwing, thrown projectiles, or non-lethal weapons such as rubber bullets and water cannons. They can also be used as short-ranged melee weapons to push back the opposing force. Most riot shields do not offer ballistic protection; ballistic shields are instead used in situations where heavily armed resistance is expected. Riot shields are used in almost every country with a standardized police force and are produced by many companies. Law enforcement often use them in conjunction with a Baton (law enforcement), baton. Riot shields ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Mask
A gas mask is a piece of personal protective equipment used to protect the wearer from inhaling airborne pollutants and toxic gases. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Most gas masks are also respirators, though the word ''gas mask'' is often used to refer to military equipment (such as a field protective mask), the scope used in this article. Gas masks only protect the user from ingesting or inhaling chemical agents, as well as preventing contact with the user's eyes (many chemical agents affect through eye contact). Most combined gas mask filters will last around 8 hours in a biological or chemical situation. Filters against specific chemical agents can last up to 20 hours. Airborne toxic materials may be gaseous (for example, chlorine or mustard gas), or particulates (such as biological warfare, biological agents). Many filters provide protection from both types. The first gas m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Armor
Body armour, personal armour (also spelled ''armor''), armoured suit (''armored'') or coat of armour, among others, is armour for a person's body: protective clothing or close-fitting hands-free shields designed to absorb or deflect physical attacks. Historically used to protect military personnel, today it is also used by various types of police ( riot police in particular), private security guards, or bodyguards, and occasionally ordinary citizens. Today there are two main types: regular non-plated body armor for moderate to substantial protection, and hard-plate reinforced body armor for maximum protection, such as used by combatants. History Many factors have affected the development of personal armor throughout human history. Significant factors in the development of armor include the economic and technological necessities of armor production. For instance full plate armor first appeared in medieval Europe when water-powered trip hammers made the formation of plates ...

Riot Protection Helmet
A riot protection helmet or riot helmet is a type of helmet designed for law enforcement and military use to protect the wearer's head, face and eyes from handheld melee weapons, and thrown projectiles such as bricks, as may be met in riot control. Many modern riot squad helmets are reinforced with materials that will protect the wearer from dangerous substances such as acids or industrial chemicals. The riot protection helmets are usually made to be able to easily fit a gas mask, especially when tear gas is being used. There have been rare cases of riot protection helmets being worn to protect against objects blown by tornadoes or fierce storms, for example in England in the 18 January 2007 gale. Description The simplest form is a hard shell with reinforced padding, and a chinstrap and a hinge-up (usually polycarbonate) visor, as in this image. These riot protection helmet visors are usually curved sideways and straight up-and-down, not curved both ways like on the older type ...

Mounted Police
Mounted police are police who patrol on horseback or camelback. Their day-to-day function is typically picturesque or ceremonial, but they are also employed in crowd control because of their mobile mass and height advantage and increasingly in the United Kingdom, UK for crime prevention and high visibility policing roles. The added height and visibility that the horses give their riders allows officers to observe a wider area, and it also allows people in the wider area to see the officers, which helps deter crime and helps people find officers when they need them. When employed for crowd control, there is a risk that some people may be trampled (resulting in injuries or death). The officer riding the horse might or might not be held legally responsible for injuries depending upon the totality of the circumstances. Mounted police may be employed for specialized duties ranging from patrol of parks and Wilderness, wilderness areas, where police cars would be impractical or noisy, ...

Police Dog
A police dog, also known as a K-9 (phonemic abbreviation of canine), is a dog that is trained to assist police and other law enforcement officers. Their duties may include searching for drugs and explosives, locating missing people, finding crime scene evidence, protecting officers and other people, and attacking suspects who flee from officers. The breeds most commonly used by law enforcement are the German Shepherd, Belgian Malinois, Bloodhound, Dutch Shepherd, and Labrador Retriever. In recent years, the Belgian Malinois has become the leading choice for police and military work due to their intense drive, focus, agility, and smaller size, though German Shepherds remain the breed most associated with law enforcement. Police dogs are used on a federal and local level for law enforcement purposes in many parts of the world. They are often assigned to what in some nations is referred to as a K-9 Unit, with a specific handler, and must remember several verbal cues and h ...

Aerial Surveillance
Surveillance aircraft are aircraft used for surveillance. They are primarily operated by military forces and government agencies in roles including intelligence gathering, maritime patrol, battlefield and airspace surveillance, observation (e.g. artillery spotting), and law enforcement. Surveillance aircraft usually carry limited defensive armament, if any. They do not require high-performance capability or stealth characteristics and may be modified civilian aircraft. Surveillance aircraft have also included moored balloons (e.g. TARS) and unmanned aerial vehicles (UAVs). History Pre World War I The French were the first to adopt hydrogen-filled balloons on the battlefield for reconnaissance. In the early 1790s, the French would deploy a hydrogen-filled balloon that held two soldiers: one who possessed a telescope, and the other would relay information to troops on the ground. These balloons did not cross into enemy lines; they were deployed on friendly lines for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
