A useful guideline in evaluating the significance of a national security-related news story first revealed by someone in the establishment press is whether other media outlets pick it up. If they don't, it's probably significant.
Six days after Wall Street Journal's Jose de Cordoba and Jay Solomon published their front-pager, "Chávez Aided Colombia Rebels, Captured Computer Files Show," the Washington Post turned out its coverage of the development by staffer Juan Forero, who pulled a few punches by failing to directly finger Venezuelan dictator Hugo Chavez:
CARACAS, Venezuela, May 14 -- High-ranking officials in Venezuela offered to help Colombian guerrillas obtain surface-to-air missiles meant to change the balance of power in their war with the Colombian government, according to internal rebel documents.
By comparison, de Cordoba and Solomon brought the Venezuelan dictator front-and-center with their May 9 lede:
BOGOTÁ, Colombia -- A cache of controversial computer files closely tying Venezuela's President Hugo Chávez to communist rebels seeking to topple Colombia's government appear to be authentic, U.S. intelligence officials say.
