Bin Laden had been a major player on the international stage. After the attacks, he was confined mostly to a section of a 38,000-square-foot compound with no internet or phone connection, out of public sight.
He was a man who got bored, experts say, and occupied himself with mainstream movies, books by Noam Chomsky and Bob Woodward, Netflix-y documentaries and porn.
"When you study terrorist groups, that's always what's striking to people, the kind of quirky, human side of them," Dan Byman, professor at Georgetown University and a senior fellow at the Brookings Institution, told The Washington Post. "Their whole life is not spent plotting around the campfire saying, 'How do we infiltrate America's defense?'
"They'll have lots of pornography, like men all over the world. A lot of the documents are complaining about bureaucracies. What's wrong with the fax machine. They're involved in the same sort of organizational problems of bureaucracies that we all have. In some cases, a lot worse."
But bin Laden did appear to be doing his part to advance al-Qaeda's aims. In the CIA's release, there are draft videos and statements by bin Laden, Islamist militant propaganda, and a personal journal that bin Laden had written in the day he died.
To anti-American terrorist groups, bin Laden was a sort of well-respected emeritus professor, Byman said. He was no longer actively involved in plots but was still trying to lend his intelligence and influence to the organization he had helped form and then expanded - while trying to prevent their implosion.
And the ideological and practical divisions were metastasizing. As The Post's Greg Miller and Peter Finn reported on a previous release, the documents included "chilling admonitions to remain focused on killing Americans" and concerns that important goals were distracted by regional fights.
"Our strength is limited," bin Laden wrote in a 2010 letter that compared the United States to a tree with branches that project across the world, according to Miller and Finn. "So our best way to cut the tree is to concentrate on sawing the trunk."
"This is a movement that historically has been highly divided," Byman said. "One thing Osama has been doing is trying to be a unifier. He was very comfortable working with people who agreed with him on one issue and disagreed with him on five. Toward the end of his life, a lot of what he was trying to do was to get groups to work together."
