For what it's worth: I work as one of few male nurses in a hospital, off at 11:30 p.m. I see co-workders leave with one arm loaded with purse, books, crochet supplies; the other hand is busy texting. No situational awareness, but they have NOT been taught better; always it's"someone else" responsible. Wake up! Heads up! Look like a predator, not prey! I leave with 150 lumen light in one hand, keys in the other; the light the only "weapon" allowed on campus.
