For those who have done the research, what are your favorite sources for the non-fighting topics related to self-defense? I'm thinking of things like de-escalation, recognizing threats, target hardening, victim selection, etc. I'm interested in both the technical sources (I'm a psychology nerd, so I'll even read a journal article of a related study) and the consumer-digestible content. Books, videos, articles, and even paid content/courses. For those with experience in security/LE/bouncing, which sources line up with what you found to work? For those who teach these things (to MA students, seminars, or to professionals), what seems to click?
