I think we all need to understand the state of the world and what a realistic "shtf" scenario would be. I think regardless of the situation whether it be a national anarchy, natural disaster, or foreign threats the first 24 hrs of life without law will be FLOODED with people who are armed and unaware, uninformed, and most likely by themselves or in small groups. These types PROBABLY will take to the streets and kill/be killed off. I think the first defense in a lawless nation is finding SECLUDED safety, seeking info on the situation, arming yourself, forming a team, THEN forming a plan.
I think that telling yourself and others what "will be" and "probably be" is a horrible mistake.
I think that preparing yourself with training, skills, gear, and equipment- knowing how to identify threats, react to them quickly, maintain flexibility- and communicating with your group while keeping everyone safe, would be so much better.
