The author focused on English-speaking countries, with attention to the United Kingdom, Australia, and Canada. These countries had a higher percentage of immigrants in their society than most industrialized countries, as well as a longer history of addressing issues regarding policing diverse societies. After providing a brief background on police relations with immigrants and native minorities in industrialized democracies, the author explains the principles outlined in the Charter and analyzes the experiences of countries in implementing programs consistent with the Charter. The Rotterdam Charter promotes the following principles: the necessity for an integrated and coordinated approach for police interaction with multi-cultural populations; the recruitment and retention of minority police; police training in positive interactions with minority citizens; relations with ethnic communities; the implementation of anti-discrimination legislation;, and guarding against stereotyping minorities as a criminal element. This paper shows that police practices that promote equality of opportunity for all in a multicultural society are an ongoing learning, management, and change process for most police agencies. Such an effort requires a long-term commitment that requires the dedication of time and resources for effecting change. 21 references
