But the revelations of widespread prisoner abuse

Wal-Mart priced it at $2.97--a year's supply of pickles for less than $3! "They were using it as a 'statement' item," says Pat Hunn, who calls himself the "mad scientist" of Vlasic's gallon jar. "Wal-Mart was putting it before consumers, saying, This represents what Wal-Mart's about. You can buy a stinkin' gallon of pickles for $2.97. And it's the nation's number-one brand."

Therein lies the basic conundrum of doing business with the world's largest retailer. By selling a gallon of kosher dills for less than most grocers sell a quart, Wal-Mart may have provided a ser-vice for its customers. But what did it do for Vlasic? The pickle maker had spent decades convincing customers that they should pay a premium for its brand. Now Wal-Mart was practically giving them away. And the fevered buying spree that resulted distorted every aspect of Vlasic's operations, from farm field to factory to financial statement.

Indeed, as Vlasic discovered, the real story of Wal-Mart, the story that never gets told, is the story of the pressure the biggest retailer relentlessly applies to its suppliers in the name of bringing us "every day low prices." It's the story of what that pressure does to the companies Wal-Mart does business with, to U.S. manufacturing, and to the economy as a whole. That story can be found floating in a gallon jar of pickles at Wal-Mart.

The existence and locations of the facilities -- referred to as "black sites" in classified White House, CIA, Justice Department and congressional documents -- are known to only a handful of officials in the United States and, usually, only to the president and a few top intelligence officers in each host country.

The CIA and the White House, citing national security concerns and the value of the program, have dissuaded Congress from demanding that the agency answer questions in open testimony about the conditions under which captives are held. Virtually nothing is known about who is kept in the facilities, what interrogation methods are employed with them, or how decisions are made about whether they should be detained or for how long.

While the Defense Department has produced volumes of public reports and testimony about its detention practices and rules after the abuse scandals at Iraq's Abu Ghraib prison and at Guantanamo Bay, the CIA has not even acknowledged the existence of its black sites. To do so, say officials familiar with the program, could open the U.S. government to legal challenges, particularly in foreign courts, and increase the risk of political condemnation at home and abroad.

But the revelations of widespread prisoner abuse in Afghanistan and Iraq by the U.S. military -- which operates under published rules and transparent oversight of Congress -- have increased concern among lawmakers, foreign governments and human rights groups about the opaque CIA system. Those concerns escalated last month, when Vice President Cheney and CIA Director Porter J. Goss asked Congress to exempt CIA employees from legislation already endorsed by 90 senators that would bar cruel and degrading treatment of any prisoner in U.S. custody.

The entertainment system was belting out the Beatles' "We Can Work It Out" when the phone rang. When Pete answered, his phone turned the sound down by sending a message to all the other local devices that had a volume control. His sister, Lucy, was on the line from the doctor's office: "Mom needs to see a specialist and then has to have

a series of physical therapy sessions. Biweekly or something. I'm going to have my agent set up the appointments." Pete immediately agreed to share the chauffeuring.
