This text interrogates, from the sphere of queer and decolonial studies, where trans* people are positioned around discussions about security. Or, in conjunctural terms, this text responds to why, even when there is evidence that these people face serious threats to their integrity and life, there are those who feel insecure in front of them. Thus, I do not intend to develop a defense of the trans “victim” or of their inherent vulnerability. Nor do I want to justify any solution to the criminal justice system. The answers seek to shed clues to locate transness in our conversations and imaginaries. This text does not have the objective or scope of describing each of the concrete modalities or expressions of subordination faced by trans* people. Instead, I explain two ways in how cissexism operates: erasure and classification. Both are important in this chapter, which explores the concrete ways in which the security dispositif positions trans* people within power relations. I argue that the notion of security of trans* persons responds not to objective data about their situation, but to the position they assume in the matrix of intelligibility. They are transmuted by modern security devices, which operate based on the delimitation of affective boundaries, to embody the identifiable other who represents the insecurity to be protected and feared. An other who is under constant surveillance to define their category or, to put it in a better way, the level of risk they represents to others.
