Shootall,
I'm not convinced that there will ever be a crises, but in reality, it doesn't matter how the crises occurs (economic collapse, civil unrest, pandemic, etc.), then end scenario is always the same. Bands of military, paramilitary, militia, citizens and criminals roaming around, executing who they want and taking what they want. In other words, think Serbia during the Bosnian conflict and ethnic cleansing.
And, if any of these groups focus on you and want you out, then you and yours are gone, period, end of story.
Sorry, but that's how I see it.
