Between 1980 and 2005, the number of federal and state prisoners grew by over 350% in the United States, from 319,598 to 1, 446,269 (Bureau of Justice Statistics, 2007;Harrison and Beck, 2006). According to one international comparison, prison populations have been increasing around the world, but the increase has been more dramatic in America, which results in the country holding roughly one fifth of all people held in penal institutions worldwide (Walmsley, 2005). Such growth is unprecedented in the history of America and raises the specter of significant threats to three dimensions of performance-accountability, efficiency, and effectiveness-which are relevant not only to prison systems in this country but also to similar systems worldwide, especially those that have experienced increased population growth.A Rynne et al. (2008, this issue) study attests to the international dimensions of prison system performance. The study is interesting in its own right as an investigation of how a prominent policy initiative, prison privatization, can influence system operations and such outcomes as riots. In particular, they uncover unanticipated effects of having the Queensland Department of Corrective Services (QDCS) operate a public facility as if it were a private one. Their outcome of interest was the occurrence of a riot 3 weeks after the opening of the Woodford Correctional Centre. As their analysis suggests, a fatal flaw in the QDCS approach seems to have been the assumption that a publicly run facility could operate as flexibly as a privately run facility, more specifically, that it could operate independently of political and institutional pressures faced by the QDCS.
