Situational awareness is the #1, frontline defense against any type of threat, IMHO.
Attacks on women in colleges, by far, are not committed by unknowns. And while situational awareness is always important, by far the vast majority of assaults on female college students come in the form of date rape situations, in which boundary setting, alcohol intake control, and the ability to make intelligent common-sense choices far outstrips just about everything else in terms of preventing said assaults.
While I'm all for college students being able to carry effective tools for self-defense, and strongly support people training in defensive skills (in addition to teaching shooting, I teach both martial arts AND women's self-defense courses and no they aren't the same thing)----by far the vast majority of date rape and sexual assaults on women on college campuses (which are by far the vast majority of assaults on women on college campuses) could have been forestalled by proper boundary setting and the ability to choose not to drink to excess.
Situational awareness is great---but most assaults on college-aged women do not happen from some attacker jumping out of the bushes at night when she is out jogging. In terms of percentages, the "stranger danger" possibilities (which do exist) are tiny compared to instead being back in a dorm room with a guy after a date when the girl has had too much to drink.
Sure, by all means make certain that girls know how to defend themselves. (Note: this isn't learning how to FIGHT. It is learning how to do enough to someone else so that you can escape. Girls of all sizes can learn this.) Carry pepper spray---sure. Knife? Well, possibly. (Not really a great self-defense weapon, really.)
But the ability to know your limits, set boundaries, clearly communicate them, not shift them under pressure (and the influence of alcohol), and not put yourself into potential situations in which leaving is not possible---THOSE are what will make a much larger difference in a girl's ability to not have to use physical self-defense techniques in the first place.
IMO, of course. But I'll note that this is something I've spent a lot of time researching in the past 20 years.
(Dorms are perfectly fine to live in. Again, if we are talking about assaults on women on college campuses, we aren't talking about people sneaking into dorms and grabbing unsuspecting women out of their rooms. Sororities are perfectly fine to live in, for the most part also.)
