Since the Dark Arts for Good Guys series started I have striven to paint an accurate picture of what social meltdown looks like en masse.
Sometime back I ran across VBS.TV put out by Spike Jonze. They are currently running an 8 part series on "the vice guide to Liberia". While its not for the faint of heart it is well worth if you've never seen first hand an apocalypse situation. Because dear people of earth they do exist, and it can happen anywhere.
Which is why Dark Arts got started to begin with. I encourage you to watch it and put it in your own context of understanding and remove the "oh it won't happen here" mindset.
