The rape didn't happen according to the medical reports and the physical examination of victim showed no sign of rape. Like or not there is not any rape sign. End of story. The reasons behind his lies Allah only knows.
If this had happened under HSM's administration and the authorities came back with "medical reports" to discredit the victim and claimed that "physical examination" of the victim showed no sign of rape, you wouldn't believe it. You only believe it now because someone you're related to is the President. You should be ashmed of yourself.
