CAT/C/USA/CO/2 page 7 25. The Committee is concerned at allegations of impunity of some of the State party’s law-enforcement personnel in respect of acts of torture or cruel, inhuman or degrading treatment or punishment. The Committee notes the limited investigation and lack of prosecution in respect of the allegations of torture perpetrated in areas 2 and 3 of the Chicago Police Department (art. 12). The State party should promptly, thoroughly and impartially investigate all allegations of acts of torture or cruel, inhuman or degrading treatment or punishment by law-enforcement personnel and bring perpetrators to justice, in order to fulfil its obligations under article 12 of the Convention. The State party should also provide the Committee with information on the ongoing investigations and prosecution relating to the above-mentioned case. 26. The Committee is concerned by reliable reports of acts of torture or cruel, inhuman and degrading treatment or punishment committed by certain members of the State party’s military or civilian personnel in Afghanistan and Iraq. It is also concerned that the investigation and prosecution of many of these cases, including some resulting in the death of detainees, have led to lenient sentences, including of an administrative nature or less than one year’s imprisonment (art. 12). The State party should take immediate measures to eradicate all forms of torture and ill-treatment of detainees by its military or civilian personnel, in any territory under its jurisdiction, and should promptly and thoroughly investigate such acts, prosecute all those responsible for such acts, and ensure they are appropriately punished, in accordance with the seriousness of the crime. 27. The Committee is concerned that the Detainee Treatment Act of 2005 aims to withdraw the jurisdiction of the State party’s federal courts with respect to habeas corpus petitions, or other claims by or on behalf of Guantánamo Bay detainees, except under limited circumstances. The Committee is also concerned that detainees in Afghanistan and Iraq, under the control of the Department of Defense, have their status determined and reviewed by an administrative process of that department (art. 13). The State party should ensure that independent, prompt and thorough procedures to review the circumstances of detention and the status of detainees are available to all detainees, as required by article 13 of the Convention. 28. The Committee is concerned at the difficulties certain victims of abuses have faced in obtaining redress and adequate compensation, and that only a limited number of detainees have filed claims for compensation for alleged abuse and maltreatment, in particular under the Foreign Claims Act (art. 14). The State party should ensure, in accordance with the Convention, that mechanisms to obtain full redress, compensation and rehabilitation are accessible to all victims of acts of torture or abuse, including sexual violence, perpetrated by its officials.
