The perceived threat grows with each terrorist attack in Europe, and with it a desire for security. A sense of security that cannot simply be created, but must be demonstrated. A security policy that reacts to the fears of the public requires swift and visible solutions: the quasi-militarisation of the police, concrete barriers, surveillance, and crisis simulation. Terrorism is a fight with unequal means. It produces a ubiquitous sense of shock and provokes strong reactions. My photos document the subtle shifts that occur in the struggle for security. These shifts operate between technologisation and improvisation, media production and research, and constitute the new infrastructure of things designed for our protection.
