I need to go shopping for personal alarm/pepper-spray type products (pretty quickly), and figure this could be useful for others around here (this time of year, especially): Short of lethally arming young women in not-so-safe areas, what would the law-enforcement types in The Corner recommend for sending girls off to urban colleges (or new, unsafe-looking dorms and apartments in their upperclassman years) with (particualrly girls)? (Also, where would you go to buy?)
