Anthony Shaffer (born 1962) is a former U.S. Army Reserve lieutenant colonel who became known for his claims about mishandled intelligence before the September 11 attacks, and for the censoring of his ghost written book Operation Dark Heart. Shaffer was a member of the Able Danger project, having joined in 1999.Following a Defense Intelligence Agency investigation into Shaffer, his access to classified information was revoked in September 2005 and his security clearance was revoked in February 2006. That revocation essentially ended Shaffer's career as an intelligence officer, both at DIA and in the Army Reserve. Shaffer is currently the president of the London Center for Policy Research.
