In total institutions, so Erving Goffman wrote about 60 years ago in Asylums, there is a 'constant conflict between human standards on one hand and institutional efficiency on the other'. Even in today's "post disciplinary" or "post authoritarian" prisons, where some of those total and oppressive characteristics have become relaxed and where new techniques of prison management have transformed and improved prison life, the question of striking a balance between dignity and security is still a daily preoccupation. This so-called 'constant conflict' surfaces in particular when inmates are being subjected to body searches and, in particular, to strip searches, when prisoners have to undress and have their naked bodies exposed to, and inspected by, prison staff. Body searches are therefore controversial; they are invasive and potentially degrading control techniques. However, at the same time they are also widely used in prison systems across the globe. Indeed, they are perceived as indispensable to prevent forbidden substances, weapons or communication devices from entering the prison. It should not come as a surprise, then, that such searches are deeply contested security measures and that they have been widely debated and regulated.
