The Shock Doctrine

Festivalgoers in Venice and Toronto who attended the premieres this weekend of “The Shock Doctrine,” a six-minute film written by the author Naomi Klein and the director Alfonso Cuarón, saw images of electroshock treatments from the 1950s, animated pages from a C.I.A. torture manual and footage of the 9/11 attacks and the 2004 tsunami. The brief movie encapsulates the thesis of a new book of the same title by Ms. Klein: That unconstrained free-market policies go hand in hand with undemocratic political policies.
