Awhen threats of racial violence are made and especially when they are made in public and by a group, it is incumbent upon the State to investigate with due diligence and expedition (1) It argues, however, that the present case is of a different nature and therefore the Committee cannot reasonably set out the same requirements to investigate as in the said opinion. Even if the requirement that it is incumbent on the police to Ainvestigate with due diligence and expedition were to apply in the present case, where the loan application was actually granted, the State party considers that the requirement was met. Although the information laid did not lead to prosecution, the handling of it by the police did afford the applicant effective protection and remedies within the meaning of article 2, paragraph 1 (d), and article 6 of the Convention. 7.8 The State party further contends that there is no basis either for criticizing the legal assessment made by the prosecutor. It is noted in this connection that not every differentiation of treatment is unlawful discrimination within the meaning of the Convention. In General Recommendation XIV on article 1, paragraph 1, of the Convention the Committee stated that Aa differentiation of treatment will not constitute discrimination if the criteria for such differentiation, judged against the objectives and purposes of the Convention, are legitimate (...). In considering the criteria that may have been employed, the Committee will acknowledge that particular actions may have varied purposes. In seeking to determine whether an action has an effect contrary to the Convention it will look to see whether that action has an unjustifiable disparate impact upon a group distinguished by race, colour, descent or national or ethnic origin.@ The decisions of both the Chief Constable and the District Public Prosecutor show that the decisions were based on the fact that differentiation of treatment that pursues a legitimate aim and respects the requirement of proportionality is not prohibited discrimination. 7.9 Finally, the State party dismisses the author's claims that questions relating to the pursuance by the police of charges against individuals are entirely up to the discretion of the police and that there is no possibility of bringing the case before the Danish courts. Firstly, it is possible to complain to the relevant District Public Prosecutor; secondly, the applicant had the possibility of filing a civil action against the bank; and thirdly, the applicant had the possibility of complaining to the Ombudsman. The effect of such complaint to the Ombudsman
