New Yorker articles tend to be fairly long and exhaustive (as is this one about the CIA's secret interrogation program).

The Black Sites

A rare look inside the C.I.A.’s secret interrogation program.

by Jane Mayer August 13, 2007

In the war on terror, one historian says, the C.I.A. “didn’t just bring back the old psychological techniques—they perfected them.”

Mohammed’s interrogation was part of a secret C.I.A. program, initiated after September 11th, in which terrorist suspects such as Mohammed were detained in “black sites”—secret prisons outside the United States—and subjected to unusually harsh treatment. The program was effectively suspended last fall, when President Bush announced that he was emptying the C.I.A.’s prisons and transferring the detainees to military custody in Guantánamo. This move followed a Supreme Court ruling, Hamdan v. Rumsfeld, which found that all detainees—including those held by the C.I.A.—had to be treated in a manner consistent with the Geneva Conventions. These treaties, adopted in 1949, bar cruel treatment, degradation, and torture. In late July, the White House issued an executive order promising that the C.I.A. would adjust its methods in order to meet the Geneva standards. At the same time, Bush’s order pointedly did not disavow the use of “enhanced interrogation techniques” that would likely be found illegal if used by officials inside the United States. The executive order means that the agency can once again hold foreign terror suspects indefinitely, and without charges, in black sites, without notifying their families or local authorities, or offering access to legal counsel.
