The document is at link. 1994 study where city and college rape reports were examined. Overall, 41% were proven to be false. The college campus reports were 50% false. "Quite unexpectedly then, we find that these university women, when filing a rape complaint, were as likely to file a false as valid charge." Keep in mind, under Obama's "Dear Colleague" Letter, the new standard on campus for 'proving' rape is the lower "more probable than not." This mentions the factors indicating a false rape report which I'd posted in a previous 'vanity': the Air Force Study by Charles P. McDowell.
