A couple of weeks ago, the Colombian government admitted that during a daring hostage rescue mission--code-named Operation Check--one of its soldiers had disguised himself as a member of the Red Cross. Then last week, Juan Manuel Santos, Colombia's defense minister, divulged that two of the soldiers had taken on the mantle of journalists. One posed as a cameraman, the other as a reporter. Both purported to be from an actual Caracas-based regional network called Telesur. They had gone so far as to take acting lessons in preparation.
