The false reporting of sexual assault and sexual abuse

As law Professor and abuse survivor Julie Macfarlane, B.A., LL.M. (London), Ph.D. (C.N.N.A.) told the independent inquiry into child sexual abuse, it is worth knowing that:
 "the false reporting of sexual assault and sexual abuse cases consistently throughout jurisdictions, if you look in the US and Canada and England and Wales, at the police numbers, it's consistently 5 to 8 per cent.  In other words, it's extremely low."
