Fear of sexual violence is a defining characteristic of the prison experience in the United States. Rape has been a key theme in the literature on imprisonment since at least the 1930s. There is evidence—from prison argot and epidemiological studies in particular—that this problem is not as ingrained in the UK. Clearly there is more at play here than sexual deprivation and the pains of confinement, which know no jurisdictional boundary. It is suggested that the answer may lie, to some extent at least, in the poisonous history of race relations in the United States: prison rape can be seen as a legacy of slavery and the lynch mob. The particularity of the US situation may also be explained in part by higher levels of violence in society more generally and a cynical attitude on the part of prison staff. In today's world the judge who sentences a young person to reform school or prison passes male rape on him as surely as the sentence. Every inmate has a very short time, once inside, to pick a 'wolf (a tough protector) or face gang rape, becoming the 'girl' of the institution, or death. Many of the prison suicides we read about can be traced to this choice. Worse, prison officers might even have sold the boy to aggressive inmates in order to keep the institution quiet. (Scacco 1982: vii) The above quotation encapsulates several of the main themes to be addressed in this paper. First, the notion that prison rape is a quotidian experience, that it is an inevitable secondary effect of incarceration. Second, that this is a recent development, peculiar to 'today's world'. Third, that the existence of this practice is so firmly rooted in prison life that it has generated its own argot. Fourth, that there is an intimate connection between the fear of sexual assault and violence (whether directed inwardly as suicide or at other prisoners in self-defence or retaliation.) Fifth, that prison staff may be complicit in the continuation of this practice. Scacco presents in stark form an argument that is found throughout the literature on imprisonment in the United States. Prisoner biographies and litigation, academic treatises, popular 'entertainment' and reform groups (such as Stop Prisoner Rape) are at one in their emphasis on the subculture of sexual violence that permeates prison life. Penal institutions are shown as crucibles of masculinity; places where distorted—and destructive—forms of male identity are forged. In this bleak view, those who do not fit the mould are destroyed. Only 'real men' can survive the unrelenting struggle for domination that marks the passage of time behind bars. According to Smith and Batiuk (1989: 30): the threat of sexual violence actually dominates the prison environment and structures much of the everyday interaction that goes on among inmates. In fact, the threat of sexual victimization becomes the dominant metaphor in terms of which almost every other aspect of 'prison reality' is interpreted.
