In London in 2011, the police withdrew protection from property while dealing with a riot. Within an hour, looters were burning people out of their homes and within a day a man was beaten to death. Same happened in Dublin, Ireland in 1916 and in Baghdad, Iraq in 2003.
Take away the man with the gun and people immediately start looting and soon will start killing. The man with the gun is exactly why they don't loot, pillage and kill.
People are looting, pillaging and killing because the guns went away. Not because their God was dying, not because their state was collapsing or their worlds were crumbling apart--meh, same things. Couldn't be because something pissed an entire society off. Couldn't be that the riot would've happened with or without the guns, and that controlling the riot with guns is an artificial way to quell any argument and is just a bandaid when nobody can or is willing to solve the reason why the riot happened to begin with. No, that couldn't be right...
So quick question: If the police went away, would you, not talking about anyone but yourself, revert into an animal and kill the next guy you saw? Usually the answer is, "No, I wouldn't, but what's to stop someone else?" Which implies everyone's stupid and barbaric and untrustworthy with any form of weapon (except the person being asked, of course, which is how statism was invented to begin with.)
