When "modern states not only claim a monopoly of the legitimate means of violence; they also routinely use the threat of violence to enforce the rule of law", the law not only becomes a form of violence but is violence. Philosopher Giorgio Agamben's concepts of state of exception and homo sacer are useful to consider within a geography of violence. The state, in the grip of a perceived, potential crisis (whether legitimate or not) takes preventative legal measures, such as a suspension of rights (it is in this climate, as Agamben demonstrates, that the formation of the Social Democratic and Nazi government's lager or concentration camp can occur). However, when this "in limbo" reality is designed to be in place "until further notice…the state of exception thus ceases to be referred to as an external and provisional state of factual danger and comes to be confused with juridical rule itself". For Agamben, the physical space of the camp "is a piece of land placed outside the normal juridical order, but it is nevertheless not simply an external space". At the scale of the body, in the state of exception, a person is so removed from their rights by "juridical procedures and deployments of power" that "no act committed against them could appear any longer as a crime"; in other words, people become only homo sacer. Guantanamo Bay could also be said to represent the physicality of the state of exception in space, and can just as easily draw man as homo sacer. In the 1970s, genocides in Cambodia under the Khmer Rouge and Pol Pot resulted in the deaths of over two million Cambodians (which was 25% of the Cambodian population), forming one of the many contemporary examples of state-sponsored violence. About fourteen thousand of these murders occurred at Choeung Ek, which is the best-known of the extermination camps referred to as the Killing Fields. The killings were arbitrary; for example, a person could be killed for wearing glasses, since that was seen as associating them with intellectuals and therefore as making them part of the enemy. People were murdered with impunity because it was no crime; Cambodians were made homo sacer in a condition of bare life. The Killing Fields—manifestations of Agamben's concept of camps beyond the normal rule of law—featured the state of exception. As part of Pol Pot's "ideological intent…to create a purely agrarian society or cooperative",
