They will never admit this to the public. Years ago the women had their own barracks and they had guards posted. Men were only allowed during posted visiting hours. If they did not have enough women to full a barracks they occupied an entire floor and men were not allowed.They have gone away from that.
Now women are mixed in in co-ed dormitories and that is when the problems started.
A lot of the sexual assaults are not actual physical assaults. Just looking at a woman for too long can get you in hot water.
