Richard Cohen: Charleston shooter’s manifesto reveals hate group helped to radicalize him

  This weekend we found out more about how the suspected Charleston church shooter, 21-year-old Dylann Storm Roof, became a violent racist extremist at such a young age.

  On his website, Roof left a 2,000-word manifesto in which he identifies himself as a white nationalist and says he was “truly awakened” to his beliefs after reading the online propaganda of the Council of Conservative Citizens, a notorious, racist hate group.
