Originally a public domain film from the US Army, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Riot control refers to the measures used by police, military, or other security forces to control, disperse, and arrest people who are involved in a riot, demonstration, or protest. If a riot is spontaneous and irrational, actions which cause people to stop and think for a moment (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 with a legitimate cause, or the riot was planned or organized. Law enforcement officers or military personnel have long used less lethal weapons such as batons and whips to disperse crowds and detain rioters. Since the 1980s, riot control officers have also used tear gas, pepper spray, rubber bullets, 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. Officers performing riot control typically wear protective equipment such as riot helmets, face visors, body armor (vests, neck protectors, knee pads, etc.), gas masks and riot shields. However, there are also cases where lethal weapons are used to violently suppress a protest or riot, as in the Boston Massacre, Haymarket Massacre, Banana Massacre, Hungarian Revolution of 1956, Kent State Massacre, Soweto Uprising, Mendiola Massacre, Bloody Sunday (1905) , Ponce massacre, Bloody Sunday (1972), Venezuelan Protest (2017), Tuticorin Massacre (2018)...
The front-line officers in a riot control are often fully armored and carry weapons such as batons, designed to be in direct contact with the crowd. These officers subdue rioters and subsequently allow the less heavily armoured, more mobile officers to make arrests where it is deemed necessary. In face of a greater threat, the riot police will be backed up with other officers equipped with riot guns to fire tear gas, rubber bullets, plastic bullets or "beanbag" rounds.
...Usually, when front-facing a riot, officers slowly walk in a line parallel to the riot's front, extending to both its ends, as they noisily and simultaneously march and beat their shields with their batons, to cause fear and psychological effects on the crowd.
Since the advent of artillery, straight roads have been of notable importance in city defense and control. Upon coming to power, Napoleon III built great avenues, referred to as anti-riot streets, into the troublesome quarters of Paris.[10] The wide straight roads also allowed for cavalry charges to subdue rioters.
In the United Kingdom, usually when large demonstrations take place that are deemed unstable, the territorial police force responsible for the demonstration in that area will usually deploy Police Support Unit personnel who are trained in riot tactics, along with normal divisional officers. If the demonstration turns violent, police will seal roads and other exits to contain protesters in a single area (known as kettling) to prevent widespread damage and wait until the protesters tire. These tactics were seen during the 2009 G-20 London summit protests and the 2010 student protests in London. Tear gas and other more offensive tactics are used as a last resort. Throughout police will be videoing or photographing protesters for future arrests, "snatch squad" tactics might also be used where several police officers, usually in protective riot gear, rush forwards, occasionally in flying wedge formation to break through the front of a crowd, with the objective of snatching one or more individuals from a riot that are attempting to control the demonstration at which they are present. The target may be a leader or a speaker, or someone who seems to be leading the crowd. This tactic was used in the 2011 England Riots, most notably by Greater Manchester Police who deployed this tactic in Manchester city centre on 9 August 2011.
A more straightforward tactic police may use is a baton charge which involves police officers charging at a crowd of people with batons and in some cases, riot shields. They run at the crowd hitting people with their batons, and in some situations use riotshields to push them away. Baton charging is designed to cause the maximum amount of pain, in the hope that they would be compelled to move away from the scene, dispersing the crowd...
