“ Police recording of false allegations of rape:The data on the pro formas limit the extent to which one can assess the police designations, but their internal rules on false complaints specify that this category should be limited to cases where either there is a clear and credible admission by the complainants, or where there are strong evidential grounds. On this basis, and bearing in mind the data limitations, for the cases where there is information (n=144) the designation of false complaint could be said to be probable (primarily those where the account by the complainant is referred to) in 44 cases, possible (primarily where there is some evidential basis) in a further 33 cases, and uncertain (including where victim characteristics are used to impute that they are inherently less believable) in 77 cases. If the proportion of false complaints on the basis of the probable and possible cases are recalculated, rates of three per cent are obtained, both of all reported cases (n=67 of 2,643), and of those where the outcome is known (n=67 of 2,284). Even if all those designated false by the police were accepted (a figure of approximately ten per cent), this is still much lower than the rate perceived by police officers interviewed in this study. A question asked of all of them was how they assessed truth and falsity in allegations and within this, 50 per cent (n=31) further discussed the issue of false allegations.A gap or a chasm?: attrition in reported rape cases. ”
