IN JULY 2012 a man calling himself Sam Bacile posted a short video on YouTube. It showed the Prophet Muhammad bedding various women, taking part in gory battles and declaring: “Every non-Muslim is an infidel. Their lands, their women, their children are our spoils.”

The film was, as Salman Rushdie, a British author, later put it, “crap”. “The Innocence of Muslims” could have remained forever obscure, had someone not dubbed it into Arabic and reposted it in September that year.

A group linked to al-Qaeda murdered America’s ambassador in Libya. Protests erupted in Afghanistan, Australia, Britain, France and India.
