This is why young women should be raised to defend themselves. Defense is both passive and active. For example, do not ever go to a fraternity party, because they are inherently unsafe, even if a group of women go together.
Do not drink a drink unless you have had control over it from the start. If you do not have it in your hand and under observation at any time, get a new drink.
If you feel threatened with sexual assault, it is imperative that you discreetly draw a knife and slash your attacker. Nothing quite says “No!” like a foot long gash that is bleeding profusely.
This is why young girls have to learn not to get drunk.
I am almost happy that my girls live in a “rich” town where there were always drinking parties. I am happy about it because they both learned at a very early age about what happens when boys and girls get fall down drunk at the Friday night football game.
It never got to the proportion cited in the story, but they knew enough not to drink and leave their friends.
They learned early that pretty girls are easy prey when they are drunk and separated from the herd.
And really, for those thinking she should carry a weapon—think about what condition this young woman was at the time. There is no way she should have been carrying a weapon. No way in hell.
