I pray that no F.B.I. agent, criminal profiler or (worst of all) news pundit ever gets a look at my bookshelves. There, alongside Swift, Plato, Lewis Carroll and Marx, you’d find the Marquis de Sade, Mickey Spillane, Hitler and Ann Coulter. Books are acquired for all kinds of reasons, including curiosity, irony, guilty pleasure and the desire to understand the enemy…but you try telling that to a G-man. It seems perfectly obvious to me that owning a copy of “Mein Kampf” doesn’t mean you’re a Nazi, but then I would say that, wouldn’t I?
