The al-Qaeda desktop computer contains voluminous "security" files devoted to, among other things, modern spycraft. The training offered is practical; students are told, for example, how to photograph a bombing target, use invisible ink, and evade police surveillance. The computer's manuals also focus on the broader history of partisan warfare and refer to an eclectic collection of role models, among them Aristotle, Jesus, Ahmed Kamel (the former head of Egyptian General Intelligence), and even the Israeli leader Menachem Begin, whose book The Revolt (1951), about his days as a terrorist fighting British rule in Palestine, is quoted approvingly at great length. The manuals devote special care to teaching recruits how to pass unnoticed in the West, and include the following advice:
a) Perfume used only after shaving—"After Shave" is written on the bottle. This type is used only on the chin and nowhere else.
b) Perfumes—marked "Lotion"—that are placed anywhere on the clothes, on the head, behind the ears, etc.
