Riot police in the context of "Protest"

A political demonstration is an action by a mass group or collection of groups of people in favor of a political or other cause or people partaking in a protest against a cause of concern; it often consists of walking in a mass march formation and either beginning with or meeting at a designated endpoint, or rally, in order to hear speakers. It is different from mass meeting.

Demonstrations may include actions such as blockades and sit-ins. They can be either nonviolent or violent, with participants often referring to violent demonstrations as "militant." Depending on the circumstances, a demonstration may begin as nonviolent and escalate to violence. Law enforcement, such as riot police, may become involved in these situations. Police involvement at protests is ideally to protect the participants and their right to assemble. However, officers don't always fulfill this responsibility and it's well-documented that many cases of protest intervention result in power abuse. It may be to prevent clashes between rival groups, or to prevent a demonstration from spreading and turning into a riot.

The militarization of police (paramilitarization of police in some media) is the use of military equipment and tactics by law enforcement officers. This includes the use of armored personnel carriers (APCs), assault rifles, submachine guns, flashbang grenades, sniper rifles, and SWAT (special weapons and tactics) teams. The militarization of law enforcement is also associated with intelligence agency–style information gathering aimed at the public and political activists and with a more aggressive style of law enforcement. Criminal justice professor Peter Kraska has defined militarization of police as "the process whereby civilian police increasingly draw from, and pattern themselves around, the tenets of militarism and the military model".

Observers have noted the militarizing of the policing of protests. Since the 1970s, riot police have fired at protesters using guns with rubber bullets or plastic bullets. Tear gas, which was developed by the United States Army for riot control in 1919, is still widely used against protesters. The use of tear gas in warfare is prohibited by various international treaties that most states have signed; however, its law enforcement or military use for domestic or non-combat situations is permitted.

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.

The Velvet Revolution (Czech: sametová revoluce) or Gentle Revolution (Slovak: nežná revolúcia) was a non-violent transition of power in what was then Czechoslovakia, occurring from 17 November to 28 November 1989. Popular demonstrations against the one-party government of the Communist Party of Czechoslovakia included students and older dissidents. The result was the end of 41 years of one-party rule in Czechoslovakia, and the subsequent dismantling of the command economy and conversion to a parliamentary republic.

On 17 November 1989 (International Students' Day), riot police suppressed a student demonstration in Prague. The event marked the 50th anniversary of a violently suppressed demonstration against the Nazi storming of Prague University in 1939 where 1,200 students were arrested and 9 killed (see Origin of International Students' Day). The 1989 event sparked a series of demonstrations from 17 November to late December and turned into an anti-communist demonstration. On 20 November, the number of protesters assembled in Prague grew from 200,000 the previous day to an estimated 500,000. The entire top leadership of the Communist Party, including General Secretary Miloš Jakeš, resigned on 24 November. On 27 November, a two-hour general strike involving all citizens of Czechoslovakia was held.
