"Retired Rear Adm. John M. Poindexter, once national security adviser to President Ronald Reagan, returned to government last month as head of a new information technology unit at the Defense Advanced Research Projects Agency (DARPA).

The Information Assurance Office was created to develop 'data mining' computer technologies for use against various 'asymmetric' adversaries, said Jan Walker, DARPA spokeswoman.

Poindexter, 65, was convicted in 1990 on five felony counts stemming from the Iran-Contra scandal. His conviction was overturned by an appeals court in 1992 on grounds that tainted evidence had been used against him.

Before his return to government, Poindexter worked for Syntek Technologies Inc. in Arlington, a DARPA contractor, Walker said." (The Washington Post, February 15, 2002)
