Gary,

I have used "The Walking Dead" show as a conversation piece with some people not about "survival" but about human nature. One friend is Eastern European and is always saying "why did they have to kill or leave that person, if they all just worked together...etc etc". And my position is, sadly, there are people they should have dealt with or abandoned sooner. To emphasise my point (that in any post apocalyptic scenario - be it Zombies (yes I feel you cringe from here mate ) or a food crisis the MOST dangerous thing will be OTHER PEOPLE.

Like those points you have already made, the trend will be that people decent into the most basic state of "surviving". In many cases that will be indirectly at the expense of others but in many cases directly so.

The example I use at work now centres on OMCGs (Outlaw Motorcycle Gangs) or MEOC (Middle Eastern Organised Crime) but can include any criminal gang/organisation. They ALREADY don't conform to any sense of social norm and happily flaunt laws and harm others for their own gain. Just how does anyone think they would behave when the rules went out the window and the constraints of society that exist now (however fragile) were no more ? They certainly would not be doing a "Toy Run" or collecting canned food for Syrian refugees. They would attempt to take control and they would use all the violence and contempt that they could. I would propose much like "ISIS" without the religious justification.

Trust will no doubt be one of the rarest commodities in existence.
