Three main points may serve as a basis for reflection:
The act of torture: in what historical, political or sociological context is it carried out?
The torturer: who is he? How is he trained?
A process of moral detachment: how does it come about? Prevention and reparation by international law alone are not enough.
To arrive at a definition of the concept of prevention, it is important to identify the key factors determining the behaviour of torturers and to decide whether the actions carried out by the people involved in torture prevention take sufficient account of these characteristics.
