E/CN.4/1996/72/Add.4 page 22 (b) Improve the training of members of the police force and the incorporation in the police of citizens from different ethnic communities; (c) Severely condemn police violence; (d) Be more respectful of human dignity in the holding centres and in cases of the refoulement or expulsion of “illegal entrants” and asylum-seekers; (e) Review the law on incitement to racial hatred, which is difficult to apply and seems to serve little purpose, and create a specific offence of racist harassment and violence and an offence of defamation with respect to an ethnic group or minority; (f) Take action to ensure that the United Kingdom is not seen as a country that rejects people from the South, particularly black minorities, in favour of nationals of countries of the North. Notes 1/ In particular, the Committee was concerned: (a) “That, notwithstanding [the] establishment ... of mechanisms for external supervision of investigations of incidents in which the police or military are allegedly involved, especially incidents that result in death or wounding of persons, as the investigations are still carried out by the police, they lack sufficient credibility” (CCPR/C/79/Add.55, para. 13); (b) “That members of some ethnic minorities including Africans and Afro-Caribbeans are often disproportionately subjected to stop-and-search practices that may raise doubts under the non-discriminatory provisions of the Covenant ...” (para. 14). The Committee also emphasized that “the treatment of illegal immigrants, asylum-seekers and those ordered to be deported gives cause for concern”, and observed “that the incarceration of persons ordered to be deported and particularly the length of their detention may not be necessary in every case and it is gravely concerned at instances of the use of excessive force in the execution of deportation orders” (para. 15). Lastly, the Committee was concerned “at the levels of support offered for the protection of cultural and ethnic diversity within the United Kingdom”. It noted further “with concern that many persons belonging to minorities frequently feel that acts of racial harassment are not pursued by the competent authorities with sufficient rigour and efficiency”. It also believed “that much remains to be done to effect changes in public attitudes and to combat and overcome racism” (para. 18).
