I'm surprised that the rate of unfounded allegations is only 20%
Working in an ER, I see a significant number of these alleged sexual assault cases falling apart due to glaring "inconsistencies" from the "victim", which suggest alterior motives, during the initial police interview. Despite these glaring inconsistencies, I observe that the female physicians and nurses doing the sexual assault kit never seem to be able to entertain any doubt about the truthfulness of the victim's claim.
