This report reflects the collaboration of Human Rights Watch and the Berkeley-Tulane Initiative on Vulnerable Populations at the Human Rights Center, University of California, Berkeley. Dr. Patrick Vinck, director of the Berkeley-Tulane Initiative, compiled and analyzed the prison admissions data in this report. Jamie Fellner, senior counsel of the US Program at Human Rights Watch, undertook additional research for the report and was its author, with Dr. Vinck’s assistance.

The report was edited at Human Rights Watch by Ian Gorvin, deputy program director; Clive Baldwin, senior legal advisor; David Fathi, director of the US Program; and Carol Chodroff, advocacy director of the US Program. Also at Human Rights Watch, Ashoka Mukpo, US program associate, Grace Choi, publications specialist, and Anna Lopiore, creative manager and photo editor provided invaluable production assistance. Ashoka Mukpo and Carly Bendzans, an intern at Human Rights Watch, also provided research assistance.

Human Rights Watch would like to thank Peter B. Lewis and the John Merck Fund for generously supporting the work of the US Program.
