(August 20, 2012) A Swedish documentary filmmaker released a film last year called "Last Chapter -- Goodbye Nicaragua." In it he admitted that he unknowingly facilitated a bombing, almost certainly orchestrated by the Sandinista government of Nicaragua, which took the lives of three reporters I worked with in Central America.

One of them, Linda Frazier, was the mother of a 10-year-old son. Her legs were torn apart by the blast, at La Penca, Nicaragua, along the border with Costa Rica, in May of 1984. She bled to death as she was being taken to the nearest hospital, in Ciudad Quesada, Costa Rica.

The admission by Peter Torbiornsson that he unwittingly took the bomber with him to the press conference was a window into the sordid world of espionage, terrorism and assassination that was an intimate part of every conflict I covered.

It exposed the cynicism of undercover operatives on all sides, men and women who lie and deceive for a living, who betray relationships, including between each other, who steal and who carry out murder.
