contributes, on the other hand, to the development of high standards of service and risk management72. Protection of whistle-blowers is also a tool for facilitating control mechanisms73. • CONCLUSIONS ON THE CONDUCTED THEMATIC VISITS In 2020, the NMPT carried out three thematic visits to assess the implementation of the CPT recommendations74 and SPT recommendations75 regarding police-operated places of detention76. The visits revealed that the recommendations of the international institutions that monitor detention places have not been implemented in key areas. In the opinion of the NMPT, the risk of ill-treatment of persons detained by police officers is very high. In order to mitigate the risk, it is necessary to implement the minimum anti-torture guarantees in the legislation and in practice. The CPT’s assessment of the lack of progress in implementing the committee’s recommendations was similar. The assessment can be found in the report on the CPT visit to Poland held in 2019 to assess the treatment of persons detained by the police77. 72 Ibid, item 9. 73 Resolution no. 1729 of 29 April 2010 of the Parliamentary Assembly of the Council of Europe on the protection of whistleblowers. 74 CPT report on the visit to Poland carried out on 11-22 May 2017, CPT/Inf (2018) 39, points 12-33. 75 SPT report on the visit to Poland carried out on 9-18 July 2018, 21 January 2020, CAT/OP/POL/ROSP/1, points 44-69. 76 The visit to the room for detained persons (RDP) at the District Police Station Warsaw VI (KMP.570.1.2020.AN), carried out on 6 February 2020, focused solely on the verification of the implementation of the CPT recommendations. The visit to the RDP at the Warsaw Police Headquarters (KMP.570.3.2020.KK), carried out on 4 March 2020, verified the degree of implementation of the SPT and CPT recommendations; the visit to the RDP at the Poviat Police Station in Piaseczno (KMP.570.6.2020.JJ) focused solely on the SPT recommendations. 77 CPT report on the visit to Poland carried out on 9-16 September 2019, CPT/Inf (2020) 31. 47
