Mass arrest

A mass arrest occurs when police apprehend large numbers of suspects at once. This sometimes occurs at protests. Some mass arrests are also used in an effort to combat gang activity. This is sometimes controversial, and lawsuits sometimes result. In police science, it is deemed to be good practice to plan for the identification of those arrested during mass arrests, since it is unlikely that the officers will remember everyone they arrested.

Historical examples

Former American President Jimmy Carter said in regards to the racial conflicts of the time, "I would be opposed to mass arrest, and I would be opposed to preventive detention. But I think that the abuses in the past have in many cases exacerbated the disharmonies that brought about demonstrations, and I think that arrest or large numbers of people without warrants ... is a contrary to our best systems of justice."

A famous mass arrest occurred on September 27, 2002, in Washington, DC in which several hundred anti-World Bank/International Monetary Fund protestors, journalists and bystanders were systematically arrested by police and charged with failure to obey a police order.

War crime

Indiscriminate mass arrests were designated a war crime in 1944 by a commission on war crimes created by the London International Assembly. Thar was one of two items added by that Commission to the list of war crimes that had been drawn up by the Commission on the Responsibility of the Authors of the War and on Enforcement of Penalties in 1919. Specifically, "indiscriminate mass arrests for the purpose of terrorizing the population" were designated as war crimes by the commission.

At the Netherlands temporary court martial in 1947, several members of the tokkeitai in the Netherlands East Indies were accused of the war crime of indiscriminate mass arrests. The applicable legislation, used by the court, was the NEI Statute Book Decree #44 of 1946, whose definition of war crimes paralleled the commission's list. Specifically, item #34 of the enumerated list of war crimes under the NEI legislation was "indiscriminate mass arrests for the purpose of terrorising the population, whether described as taking hostages or not". The court understood the definition of such unlawful mass arrests to be as "arrests of groups of persons firstly on the ground of wild rumours and suppositions, and secondly without definite facts and indications being present with regard to each person which would justify his arrest". It added commentary on indiscriminate mass arrests that are for the purpose of terrorizing the populace by stating that they "contained the elements of systematic terrorism for nobody, even the most innocent, was any longer certain of his liberty, and a person once arrested, even if absolutely innocent, could no longer be sure of health and life".
