A hidden world, growing beyond control

CIA Director Leon Panetta, who was also interviewed by The Post last week, said he's begun mapping out a five-year plan for his agency because the levels of spending since 9/11 are not sustainable. "Particularly with these deficits, we're going to hit the wall. I want to be prepared for that," he said. "Frankly, I think everyone in intelligence ought to be doing that."

In an interview before he resigned as the director of national intelligence in May, retired Adm. Dennis C. Blair said he did not believe there was overlap and redundancy in the intelligence world. "Much of what appears to be redundancy is, in fact, providing tailored intelligence for many different customers," he said.

Blair also expressed confidence that subordinates told him what he needed to know. "I have visibility on all the important intelligence programs across the community, and there are processes in place to ensure the different intelligence capabilities are working together where they need to," he said.

Weeks later, as he sat in the corner of a ballroom at the Willard Hotel waiting to give a speech, he mused about The Post's findings. "After 9/11, when we decided to attack violent extremism, we did as we so often do in this country," he said. "The attitude was, if it's worth doing, it's probably worth overdoing."

Outside a gated subdivision of mansions in McLean, a line of cars idles every weekday morning as a new day in Top Secret America gets underway. The drivers wait patiently to turn left, then crawl up a hill and around a bend to a destination that is not on any public map and not announced by any street sign.
Liberty Crossing tries hard to hide from view. But in the winter, leafless trees can't conceal a mountain of cement and windows the size of five Wal-Mart stores stacked on top of one another rising behind a grassy berm. One step too close without the right badge, and men in black jump out of nowhere, guns at the ready.

Past the armed guards and the hydraulic steel barriers, at least 1,700 federal employees and 1,200 private contractors work at Liberty Crossing, the nickname for the two headquarters of the Office of the Director of National Intelligence and its National Counterterrorism Center. The two share a police force, a canine unit and thousands of parking spaces.

Liberty Crossing is at the center of the collection of U.S. government agencies and corporate contractors that mushroomed after the 2001 attacks. But it is not nearly the biggest, the most costly or even the most secretive part of the 9/11 enterprise.

In an Arlington County office building, the lobby directory doesn't include the Air Force's mysteriously named XOIWS unit, but there's a big "Welcome!" sign in the hallway greeting visitors who know to step off the elevator on the third floor. In Elkridge, Md., a clandestine program hides in a tall concrete structure fitted with false windows to look like a normal office building. In Arnold, Mo., the location is across the street from a Target and a Home Depot. In St. Petersburg, Fla., it's in a modest brick bungalow in a run-down business park.
