premise: The cover package reviews the century's top 10 crimes, including the St. Valentine's Day Massacre of seven mobsters by Al Capone's henchman; the brutal 1955 murder of 14-year-old Emmett Till , which galvanized support for the civil rights movement; and the Manson family rampage , which ended the social experimentation of the '60s on a sour note.
hypothesis: It doesn't review any crimes.
