I always view accounts of social cohesion breakdons with extreme skepticism. This is not to say that they won't happen, just that they're rare, and generally wouldn't happen during a natural disaster. Obviously, the prevalence of firearms in US society makes some problems more acute than in other countries - there will always be fringe elemenst of any society that can profit from disorder, and in the US they're armed with semiautomatic weapons, making them more disruptive.
There were sufficiently different explanations of events in New Orleans to make me suspect that in fact most reports of complete social breakdown were bogus or exagerated. Here in Portugal many newspapers showed pictures from US media side-by-side depicting the same event (survivors wading in water with supplies taken from stores in hand) noting the radically different captions depending on race (blacks "were looters using the general disorder and natural calamity to rampage and steal" whereas whites "were exeercising their ingenuity and survival spirit after securing supplies from a nearby store"). It seems to me that it's in the interest of the powers that be do show that without them them in charge things would totally breakdown and we will all be in risk of being killed.
Let me paste some excerpts from "What we learned from Katrina", from Ran Prieur's site (
http://www.ranprieur.com):
"... Ordinary people are competent and decent when you strip away the system and the stupid roles it requires us to play. A catastrophe is a huge opportunity for us to learn to help each other as equals, for people suddenly free of jobs and cars and television to rediscover their aliveness, to come together and build something beautiful. This will not be permitted. It's the Federal Emergency "Management" Agency. People with their survival needs met and free time are a huge threat to management. The reason they sent troops to New Orleans instead of food and water, the reason police violently broke up groups of people who managed to come together and take care of each other, the reason they sealed off the whole city except for official evacuation buses in which people were treated worse than cattle, is the same reason you have to have a job to eat and occupy space, and the same reason they had to kill the Indians: It is so deeply ingrained in human nature to build cooperative non-coercive communities, that the domination system cannot afford to give us an inch. (...) "Roving gangs" happen but they're overrated. They do not attack hard targets and fight to the last man like in the movies. The "lawlessness" in New Orleans confirms what I wrote in The Slow Crash, which is just what anyone can see in history: Even when people are starving, it is very rare that someone will kill to steal food. Low-status sociopaths attack easy targets: a pretty young woman will be raped. A rich tourist will be robbed. If you're defending a private home or business with a grim look and a big gun, you almost certainly won't have to use it."
And from Slow Crash:
(...)"I forgot to mention the last thing the guy said, which was that he had told the same story many times to people in the US and the response was always, "That wouldn't happen here -- it'd be total anarchy, people would be at each other's throats."
. This shows how effective the propaganda is but it's interesting just how wrong those predictions were, although the propaganda system was able to maintain the illusion perfectly for people (in the mainstream) outside New Orleans. The system tells us that without it we would be living in anarchy but in actual fact we would be living in community and that's what the troops were doing in New Orleans -- preventing outbreaks of community, not outbreaks of anarchy."
I am not sure he is 100% certain, but he certainly makes a good point.
