The author first discusses problems of undertaking comparative research into policewomen and the need for caution in the interpretation of the results, given the opportunistic nature of the data collection (data were obtained from delegates attending international conferences of policewomen). Notwithstanding limitations of the research design, several observations are drawn from the data: the ubiquitous nature of sex discrimination and sexual harassment in the police service; greater similarities between officers from the British Isles and Australia, with greatest divergence evident from those serving in the United States; and variation in terms of the frequency with which support strategies are adopted by policewomen. Explanations in terms of aspects of masculinity and women's networking are offered to account for differences between the policewomen. The study concludes that the reluctance to accept women on equal terms in policing seems universal, as does the presence of discriminatory and harassing treatment. Equal opportunities policies and procedures are in place; and yet these, together with police union activities, are the least likely sources of support for women police officers. There is still a heavy reliance on self-help for advancement. Police unions/staff associations and senior police management should intervene more directly in the promotion of gender equity. 3 figures and 42 references
