The good Jihadi

In North Sumatra, a former Indonesian radical has opened a boarding school for the children of terrorists to prevent their futures from looking like his own past. Words by: Gabrielle Lipton Photography by: Albert Ivan Damanik Wat happens when children begin to realise that their parents are following a different path?
