U.S. Department of Justice announces arrests of four people in two separate espionage cases. One case involves a former Boeing Corp. employee who was charged with economic espionage and other crimes. The other involves three people who face charges that they conspired to disclose national defense information. A Department of Defense employee and two New Orleans residents were arrested for an alleged espionage scheme that began in January 2006. If convicted, the four could face up to 15 years in prison and a $500,000 fine.”]
