U.S agents charged with disrupting and dismantling al Qaeda are hoping Sunday's harrowing raid of Osama bin Laden's Pakistani compound yields valuable financial clues that could help them expose the underpinnings of the entire organization, including the identities of the major donors who have bankrolled the terror network.
American authorities are ready to follow the money, experts say, hoping detailed ledgers and financial records were scooped up during the raid in which bin Laden was killed. They say any wealthy financiers whose donations helped support the bin Laden terror network now have reason to be nervous.
"Al-Qaeda has traditionally been funded by deep-pocket donors," said Stuart Levey, who served as the Treasury Department's undersecretary for terrorism and financial intelligence and is now a senior fellow at the Council on Foreign Relations. "If people have been giving money, and they don't know yet whether their name is being identified in this intelligence, or that their name might be on a list of potential donors, they might have real reason to worry."
Top counterterror officials said the Navy SEALs who conducted the raid on bin Laden's fortified lair did not leave empty handed. But they have not disclosed what exactly they carried away along with bin Laden's corpse.
John Brennan, the president's chief counterterrorism advisor, told reporters the military team "took advantage of their time there to make sure that we were able to acquire whatever material we thought was appropriate."
He wouldn't describe in detail what they found, but said the quantity of the material was not as encouraging as its quality. A special CIA team has been designated to go through it.
"We feel as though this is a very important time to continue to prosecute this effort against al Qaeda, take advantage of the success of yesterday and to continue to work to break the back of al Qaeda," Brennan said.
Levey noted that in Iraq, detailed financial books were discovered in 2007 that provided a roadmap for al Qaeda in Iraq's financial structure. In 2010, a drone strike by U.S. forces took out the man believed to be al Qaeda's chief financial officer, Saeed al-Masri. Little is known about the bookkeeping that occurred after that.
"Others replaced him, but we don't know that they exerted the same control," Levey said.
Whether bin Laden took over that work himself, or kept those records with him remains unclear. But if he did, Levey said, those records could do lasting damage to the entire al Qaeda network.
Investigators are relishing the chance to put their hands on actual records that will enable them to dissect bin Laden's operations, said John Nagl, a counter-terrorism expert who serves as president of the Center for a New American Security. His ability to operate in the world without leaving a trace of himself is what helped him evade capture for more than a decade.
"He did a very good job in hiding himself from the outside world," Nagl said. "He cut himself off from all electronic emissions."
