Human shields have been making headlines for some time. Before the recent fray between ISIS and Iraqi governmental forces in Fallujah, the United Press International released an article entitled “Iraqi forces halt Fallujah advance amid fears for 50,000 human shields.” Indeed, not a day has passed in the last several months without an array of newspapers mentioning human shields in different theatres of violence: from Syria, where ISIS fighters fled Manbij in convoys apparently using human shields, through Kashmir, where “army and police used civilians as human shields in operations against militants,” to Ukraine, where pro-Russian separatists were accused of using international observers as shields.
The trope is promulgated by an array of actors. Liberal democratic states are not the only ones who are warning the world of the increasing use of human shields; rather authoritarian regimes as well as a variety of local and international organizations of different kinds, from the Red Cross and human rights NGOs to the United Nations are also invoking the term. In a recent confidential United Nations report, Houthi rebels were blamed for concealing “fighters and equipment in or close to civilians with the deliberate aim of avoiding attack.”
Although different forms of human shielding have likely been mobilized since the invention of war, its quotidian use is a completely novel phenomenon. Why, one might ask, has this term suddenly become so pervasive?
Legally speaking, human shields refer to the use of civilians as defensive weapons in order to render combatants or military sites immune from attacks. The idea behind the term is that civilians, who are protected under international law, should not be exploited to gain a military advantage.
While most people will undoubtedly be familiar with this definition, less known is the fact that international law not only prohibits the use of human shields but also renders it legitimate for militaries to attack areas being “protected” by human shields.
The US Air Force, for example, maintains that "lawful targets shielded with protected civilians may be attacked, and the protected civilians may be considered as collateral damage, provided that the collateral damage is not excessive compared to the concrete and direct military advantage anticipated by the attack." Along similar lines, the 2015 Department of Defense Law of War Manual underscores the importance of the principle of proportionality, it also notes that, “otherwise lawful targets involuntarily shielded with protected civilians may be attacked… provided that the collateral damage is not excessive compared to the concrete and direct military advantage anticipated by the attack.”
What all this means, quite simply, is that human shields can be legally killed so long as the deployment of violence does not breach the principle of proportionality—which requires belligerents to refrain from causing damage disproportionate to the military advantage to be gained.
It now appears that police forces the world over are adopting a similar perspective as they confront protests and riots. The motivation behind the adoption of such guidelines by domestic and international actors is clear: it allows security forces to relax the rules of engagement, while framing those who deploy shields as morally deplorable and in breach of international law.
Preemptive Legal Defense
Given the strategic and pervasive adoption of the phrase human shields, it seems clear that the term is not only being deployed as a descriptive expression to depict the use of civilians as weapons, but also as a kind of preemptive legal defense against the accusations of having killed or injured them. Put differently, if any one of Fallujah’s 50,000 civilians is killed during an anti-ISIS onslaught, then it is not the US-backed attacking forces that are to blame, but rather ISIS itself, which illegally and immorally used civilians as shields. Moreover, it increasingly appears that it is enough to claim--in advance-- that the enemy is using human shields in order to warrant the killing of non-combatants.
Even though it is undeniable that many militaries and non-state armed groups do, in fact, use human shields, the potential ramifications of the mere accusation are extremely worrisome. In other words, by claiming that the other side is using human shields, the attacking force provides itself with a preemptive legal defense.
To understand fully the implications of this framing it is imperative to take into account that urban areas, as Stephen Graham from Newcastle University put it, "have become the lightning conductors for our planet's political violence." The fact that warfare currently shapes urban life in many areas around the globe means that civilians occupy and will continue to occupy the front lines of much of the fighting. This leaves them extremely vulnerable to being framed as human shields, since it would be enough to say in advance that the residents of a city are shields for their deaths to be legal and justified.
Insofar as this is the case, then the preemptive legal defense may very well be used as part of a horrifying process aimed at legalizing and normalizing the massive slaughtering of civilians.
