Mass murder

Twenty-six republicans were assassinated by fascists that belonged to Franco's Nationalists at the beginning of the Spanish Civil War, between August and September of 1936. This mass grave is placed at the small town named as Estépar, in Northern Spain. The excavation occurred in July–August of 2014.

Mass murder (sometimes interchangeable with "mass destruction") is the act of murdering several or more people, typically simultaneously or over a relatively short period of time. The FBI defines mass murder as murdering four or more persons during an event with no "cooling-off period" between the murders. A mass murder typically occurs in a single location where one or more people kill several others. Many acts of mass murder end with the perpetrator(s) dying by suicide or suicide by cop.

A mass murder may be committed by individuals or organizations whereas a spree killing is committed by one or two individuals. Mass murderers differ from spree killers, who kill at two or more locations with almost no time break between murders and are not defined by the number of victims, and serial killers, who may kill people over long periods of time. Mass murder is the hypernym of genocide, which requires additional criteria.

Mass murder is also defined as the intentional and indiscriminate murder of a large number of people by government agents; for example, shooting unarmed protestors, throwing grenades into prison cells, and randomly executing civilians. The largest mass killings in history have been governmental attempts to exterminate entire groups or communities of people, often on the basis of ethnicity or religion because of dislike or intolerance. Some of these mass murders have been found to be genocides and others to be crimes against humanity, but often such crimes have led to few or no convictions of any type.

Mass murder by a state

The concept of state-sponsored mass murder covers a range of potential killings. It is defined as the intentional and indiscriminate murder of a large number of people by government agents. Examples are shooting of unarmed protesters, lobbing of grenades into prison cells, and random execution of civilians. Other examples of state-sponsored mass murder include:

• Deliberate massacres of captives or civilians during wartime by the state's military forces, such as these committed by Genghis Khan, the Golden Horde, the troops of Vlad the Impaler, the Empire of Japan, the Soviet Union, and Nazi Germany during the Second Sino-Japanese War and World War II: the Nanjing Massacre, the Katyn Forest Massacre of Polish citizens in 1940 and the massacres of political prisoners after the launch of Operation Barbarossa, the Three Alls Policy, the massacre of Soviet Jews at Babi Yar, the mass murder of the Hungarian and German population in Vojvodina in the "Vengeance of Bacska, the murder of 24 unarmed villagers by British troops in the Batang Kali massacre during the Malayan Emergency, the murder of Vietnamese civilians by American soldiers in the My Lai Massacre during the Vietnam War, and in recent times mass murder of civilian eg.Al-Qubeir massacre in Syria by the Syrian army during the Syrian Civil War.
• Actions in which the state caused the death of large numbers of people, which political scientist R. J. Rummel calls "democide", which, in addition to the cases above, may include man-made disasters caused by the state, such as the Holodomor in the Soviet Union, the Khmer Rouge years in Cambodia, the mass killings in Indonesia during Suharto's rise to power, and the famines and poverty caused by the Great Leap Forward and the Cultural Revolution in the People's Republic of China.

Mass murder by terrorist organizations

Being more like mass murdering organizations, many terrorist groups in recent times have used the tactic of killing many victims to fulfill their political aims. Such organizations have had success in their aims like the 1983 Beirut barracks bombing in October 1983 by the Islamic Jihad Organization, the September 11 attacks in September 2001 by Al-Qaeda, and the November 2015 Paris attacks in November 2015 by the Islamic State of Iraq and the Levant.

Mass murder by individuals

Mass murderers may fall into any of a number of categories, including killers of family, of coworkers, of students, and of random strangers. Their motives for murder vary. A notable motivation for mass murder is revenge, but other motivations are possible, including the need for attention or fame.

Student Seung-Hui Cho killed 32 people on Virginia Tech's campus in 2007.

Examples of mass murderers include King Dipendra of Nepal, Anders Behring Breivik, Timothy McVeigh, Adam Lanza, Cho Seung-Hui, Eric Harris, Dylan Klebold, Robert Steinhäuser, Pekka-Eric Auvinen, Matti Juhani Saari, Tim Kretschmer, William Unek, Campo Elías Delgado, Jeff Weise, Woo Bum-kon, Martin Bryant, Ahmed Ibragimov, Baruch Goldstein, Robert Bales, Omar Thornton, Nidal Malik Hasan, James Holmes, Dylann Roof, Andreas Lubitz, and Elliot Rodger.

Acting on the orders of Joseph Stalin, Vasili Blokhin's war crime killing of 7,000 Polish prisoners of war, shot in 28 days, is notable as one of the most organized and protracted mass murders by a single individual on record.

Law enforcement response and countermeasures

Analysis of the Columbine High School massacre and other incidents where law enforcement officers waited for backup has resulted in changed recommendations regarding what victims, bystanders, and law enforcement officers should do. Average response time by law enforcement to a mass shooting is typically much longer than the time the shooter is engaged in killing. While immediate action may be extremely dangerous, it may save lives which would be lost if victims and bystanders involved in the situation remain passive, or law enforcement response is delayed until overwhelming force can be deployed. It is recommended that victims and bystanders involved in the incident take active steps to flee, hide, or fight the shooter and that law enforcement officers present or first arriving at the scene attempt immediately to engage the shooter. In many instances, immediate action by victims, bystanders, or law enforcement officers has saved lives.

Criticism of the analytical category "mass murder"

Commentators have pointed out that there are a wide variety of ways that homicides with more than several victims might be classified. Such incidents can be, and have been even in recent decades, classified many different ways including "as a mass shooting; as a school shooting; as mass murder; as workplace violence...; as a crime involving an assault rifle; as a case of a mentally ill person committing acts of violence; and so on."

How such rarely occurring incidents of homicide are classified tends to change significantly with time. "In the 1960s and 1970s,... it was understood that the key feature of [a number of such] cases was a high body count. These early discussions of mass murder lumped together [a variety of] cases that varied along what would come to be seen as important dimensions:

• Time: Did the killings occur more or less simultaneously, or did they extend over several days, months, or years?
• Place: Did the killings occur in a single location, or in a variety of places?
• Method: How were the victims killed?"

In the late decades of the 20th century and early years of the 2000s, the most popular classifications moved to include method, time and place. While such classifications may assist in gaining human meaning, as human-selected categories, they can also carry significant meaning and reflect a particular point of view of the commentator who assigned the descriptor.
