Well, well, well. Isn't this interesting:

WASHINGTON — The Central Intelligence Agency in 2004 hired outside contractors from the private security contractor Blackwater USA as part of a secret program to locate and assassinate top operatives of Al Qaeda, according to current and former government officials.

Executives from Blackwater, which has generated controversy because of its aggressive tactics in Iraq, helped the spy agency with planning, training and surveillance. The C.I.A. spent several million dollars on the program, which did not capture or kill any terrorist suspects.

The fact that the C.I.A. used an outside company for the program was a major reason that Leon E. Panetta, the new C.I.A. director, became alarmed and called an emergency meeting to tell Congress that the agency had withheld details of the program for seven years, the officials said.

It is unclear whether the C.I.A. had planned to use the contractors to capture or kill Qaeda operatives, or just to help with training and surveillance. American spy agencies have in recent years outsourced some highly controversial work, including the interrogation of prisoners. But government officials said that bringing outsiders into a program with lethal authority raised deep concerns about accountability in covert operations.

Officials said that the C.I.A. did not have a formal contract with Blackwater for this program but instead had individual agreements with top company officials, including the founder, Erik D. Prince, a politically connected former member of the Navy Seals and the heir to a family fortune. Blackwater’s work on the program actually ended years before Mr. Panetta took over the agency, after senior C.I.A. officials themselves questioned the wisdom of using outsiders in a targeted killing program.
