ArsonW
Arson

Arson is a crime of willfully and maliciously setting fire to or charring property. Though the act typically involves buildings, the term arson can also refer to the intentional burning of other things, such as motor vehicles, watercraft, or forests. The crime is typically classified as a felony, with instances involving a greater degree of risk to human life or property carrying a stricter penalty. A common motive for arson is to commit insurance fraud. In such cases, a person destroys their own property by burning it and then lies about the cause in order to collect against their insurance policy.

A car bomb, lorry bomb, or truck bomb, also known as a vehicle-borne improvised explosive device (VBIED), is an improvised explosive device designed to be placed and detonated in an automobile or other vehicles.

Death squadW
Death squad

A death squad is an armed group whose primary activity is carrying out extrajudicial killings or forced disappearances as part of political repression, genocide, ethnic cleansing, or revolutionary terror. Except in rare cases where they are formed by an insurgency, domestic or foreign governments actively participate in, support, or ignore the death squad's activities. Death squads are distinct from assassination due to their permanent organization and the larger number of victims who may not be prominent individuals. Other violence, such as rape, torture, arson, or bombings may be carried out alongside murders. They may comprise a secret police force, paramilitary militia groups, government soldiers, policemen, or combinations thereof. They may also be organized as vigilantes. When death squads are not controlled by the state, they may consist of insurgent forces or organized crime, such as the ones used by cartels.

DehumanizationW
Dehumanization

Dehumanization is the denial of full humanness in others and the cruelty and suffering that accompanies it. A practical definition refers to it as the viewing and treatment of other persons as though they lack the mental capacities that are commonly attributed to human beings. In this definition, every act or thought that regards a person as "less than" human is dehumanization.

HostageW
Hostage

A hostage is a person seized by a criminal abductor in order to compel another party such as a relative, employer, law enforcement or government to act, or refrain from acting, in a certain way, often under threat of serious physical harm to the hostage(s) after expiration of an ultimatum. The 1911 edition of the Encyclopædia Britannica defines a hostage as "a person who is handed over by one of two belligerent parties to the other or seized as security for the carrying out of an agreement, or as a preventive measure against certain acts of war."

Human shieldW
Human shield

Human shield is a legal, military and political term denoting a non-combatant who is either forced or volunteers to shield a legitimate military target in order to deter the enemy from attacking it. The use of human shields as a resistance measure was popularized by Mahatma Gandhi as a weapon of peace. On the other hand, the weaponization of civilians has also developed as a tactic by some non-state actors like ISIS, a tactic developed by Germany in the Franco-Prussian War in 1870.

HumiliationW
Humiliation

Humiliation is the abasement of pride, which creates mortification or leads to a state of being humbled or reduced to lowliness or submission. It is an emotion felt by a person whose social status, either by force or willingly, has just decreased. It can be brought about through intimidation, physical or mental mistreatment or trickery, or by embarrassment if a person is revealed to have committed a socially or legally unacceptable act. Whereas humility can be sought alone as a means to de-emphasize the ego, humiliation must involve other person(s), though not necessarily directly or willingly.

KidnappingW
Kidnapping

In criminal law, kidnapping is the unlawful transportation, asportation and confinement of a person against their will. Thus, it is a composite crime. It can also be defined as false imprisonment by means of abduction, both of which are separate crimes that when committed simultaneously upon the same person merge as the single crime of kidnapping. The asportation/abduction element is typically but not necessarily conducted by means of force or fear. That is, the perpetrator may use a weapon to force the victim into a vehicle, but it is still kidnapping if the victim is enticed to enter the vehicle willingly, e.g., in the belief it is a taxicab.

Letter bombW
Letter bomb

A letter bomb, also called parcel bomb, mail bomb, package bomb, note bomb, message bomb, gift bomb, present bomb, delivery bomb, surprise bomb, postal bomb, or post bomb, is an explosive device sent via the postal service, and designed with the intention to injure or kill the recipient when opened. They have been used in terrorist attacks such as those of the Unabomber. Some countries have agencies whose duties include the interdiction of letter bombs and the investigation of letter bombings. The letter bomb may have been in use for nearly as long as the common postal service has been in existence, as far back as 1764.

LynchingW
Lynching

Lynching is an extrajudicial killing by a group. It is most often used to characterize informal public executions by a mob in order to punish an alleged transgressor, punish a convicted transgressor, or intimidate. It can also be an extreme form of informal group social control, and it is often conducted with the display of a public spectacle for maximum intimidation. Instances of lynchings and similar mob violence can be found in every society.

PiracyW
Piracy

Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and other valuable items or properties. Those who engage in acts of piracy are called pirates, while dedicated ships that are used by them are called pirate ships. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean and Mediterranean civilizations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding. Historic examples include the waters of Gibraltar, the Strait of Malacca, Madagascar, the Gulf of Aden, and the English Channel, whose geographic structures facilitated pirate attacks. A land-based parallel is the ambushing of travelers by bandits and brigands in highways and mountain passes. Privateering uses similar methods to piracy, but the captain acts under orders of the state authorizing the capture of merchant ships belonging to an enemy nation, making it a legitimate form of war-like activity by non-state actors.
