CAT/C/DEU/CO/5 Exercise of jurisdiction 28. The Committee is seriously concerned at the reported reluctance on part of the State party to exercise jurisdiction over allegations of torture and ill-treatment of persons rendered abroad, including the case of Khaled El-Masri, in violation of article 5 of the Convention. In addition, the Committee is concerned at the absence of information from the State party whether Khaled El-Masri has received any remedies, including compensation, in accordance with article 14 of the Convention (arts. 5 and 14). The State party is urged to observe article 5 of the Convention which requires that the criteria for exercise of jurisdiction are not limited to nationals of the State party. The State party should also inform the Committee about the remedies, including adequate compensation provided, to Khaled El-Masri, in accordance with article 14 of the Convention. Training of law enforcement personnel 29. While taking note of the training of the federal and Länder law enforcement personnel on the Convention, constitutional guarantees and public and national criminal and procedural law, the Committee expresses its concern at the lack of specific training to all professionals directly involved in the investigation and documentation of torture as well as medical and other personnel involved with detainees and asylum-seekers on the Manual on Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (Istanbul Protocol). The Committee is also concerned that the training on the Istanbul Protocol, to be introduced next year in all the Länder, is designed to focus on detecting physical but not psychological traces of torture. The lack of training on the absolute prohibition of torture in the context of instructions issued to the intelligence services is yet another source of concern (arts. 2, 10 and 16). The Committee recommends that the State party: (a) Ensure that all law enforcement, medical and other personnel involved in the holding in custody, interrogation or treatment of any individual subjected to any form of arrest, detention or imprisonment and the documentation and investigation of torture are provided, on a regular basis, with training on the Manual on Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (Istanbul Protocol), requiring the identification of both physical and psychological consequences for victims of torture; (b) Ensure that such training is also provided to personnel involved in asylum determination procedures, and make the existing publications and training tools on the Istanbul Protocol available on the Internet; and (c) Include systematic reference to the absolute prohibition of torture in the instructions issued to the intelligence services. Identification of police officers 30. The Committee is concerned by the State party’s information that police officers, except in Brandenburg and Berlin, are not obliged to wear identification badges showing their number or name during the exercise of their functions and that even in those two Länder the wearing of badges might be withdrawn in order to protect the safety and interests of the police officers, according to the State party. This practice has reportedly hindered in many cases the investigation and holding to account of the police officers allegedly implicated in ill-treatment, including the incidents of the excessive use of force in the context of demonstrations. According to a study commissioned by the Berlin Police, some 10 per cent of cases of alleged ill-treatment by the police could not be elucidated or prosecuted because of lack of identification (arts. 12, 13 and 14). 10
