The prisoner in perhaps the most iconic photo from Abu Ghraib, the hooded man standing on a box with electrical wires attached to his hands, was being interrogated by the CID itself for his alleged role in the kidnapping and murder of two American soldiers in Iraq. As noted in Chapter 4, "Electrical Wires," a CID spokesman confirmed to Salon that a CID agent was suspended in fall 2004 pending an investigation and later found "derelict in his duties" for his role in prisoner abuse. Salon could not confirm whether the agent was punished for his role in the abuse of the hooded man connected to electrical wires, known to military personnel as "Gilligan."

The CID documentation, as well as other reporting, confirmed that a March 11 New York Times article identifying the prisoner in the iconic photo as Ali Shalal Qaissi, a local Baath Party member under Saddam Hussein and now a prisoners' rights advocate in Jordan, was incorrect. The CID photo archive confirms that a prisoner matching Qaissi's description -- he has a deformed left hand -- and known by the nickname "The Claw" was held at the prison and photographed by military police on the same night as the mock electrocution, but he was not the one standing on the box and attached to wires. The CID materials say all five photos of the hooded man were the prisoner known as "Gilligan." It remains possible that Qaissi received similar treatment, but there is no record of that abuse.

Chapter 5, "Other Government Agencies," tells the story behind photos of the mangled corpse of Manadel al-Jamadi, known as the "Ice Man," who died during interrogation by a CIA officer. No one at the CIA has been prosecuted, even though al-Jamadi's death was ruled a homicide. The chapter adds new detail about the CIA's role in the prison drawn from Christopher Brinson's testimony to CIA investigators.

As explained in Chapter 1, "Standard Operating Procedure," some of the 279 photos and 19 videos in the archive depict controversial interrogation tactics employed in cellblock 1A. Among the examples of abuse on display in the photos were techniques sanctioned by Secretary of Defense Donald Rumsfeld for use on "unlawful enemy combatants" in the "war on terror." These include forced nudity, the use of dogs to terrorize prisoners, keeping prisoners in stress positions -- physically uncomfortable poses of various types -- for many hours, and varieties of sleep deprivation. Some of these techniques migrated from Guantánamo and Afghanistan to Iraq in 2003. (The abuse depicted in the Abu Ghraib photos did not occur during interrogation sessions, but in some cases military guards allege they were encouraged to "soften up" detainees for interrogation by higher-ranking military intelligence officers.)

Military intelligence personnel and civilian contractors employed by the military appear in some of the photographs with the military guards, and entries from a prison logbook captured in the archive show that in some cases military police believed their tough tactics were being approved by -- and in some cases ordered by -- military intelligence officers and civilian contractors. The logbook also documents prisoner rioting and the regular presence of multiple OGA (other government agency) detainees held in the military intelligence wing.

Three years and at least six Pentagon investigations later, we now know that many share the blame for the outrages that took place at Abu Ghraib in the fall of 2003. The abuse took place against the backdrop of rising chaos in Iraq. In those months the U.S. military faced a raging insurgency for which it hadn't planned. As mortar attacks rained down on the overcrowded prison -- at one point there were only 450 guards for 7,000 prisoners -- its command structure broke down. At the same time, the pressure from the Pentagon and the White House for "actionable intelligence" was intense, and harsh interrogation techniques were approved to obtain it. Bush administration lawyers, including Alberto Gonzales and John Yoo, had already created a radical post-9/11 legal framework that disregarded the Geneva Conventions and other international laws governing the humane treatment of prisoners in the "war on terror." Intelligence agencies such as the CIA were apparently given the green light to operate by their own set of secret rules.

But while the Pentagon's own probes have acknowledged that military commanders, civilian contractors, the CIA and government policymakers all bear some responsibility for the abuses, to date only nine enlisted soldiers have been prosecuted for their crimes at Abu Ghraib (see sidebar). An additional four soldiers and eight officers, including Brinson, Pappas and Army Reserve Brig. Gen. Janis Karpinski, who was in charge of military police at Abu Ghraib, have been reprimanded. (Pappas and Karpinski were also relieved of their posts.) To date no high-level U.S. officials have been brought to justice in a court of law for what went on at Abu Ghraib.

Our purpose for presenting this large catalog of images remains much the same as it was four weeks ago when we first published a much smaller number of Abu Ghraib photos that had not previously appeared in the media. As Walter Shapiro wrote, Abu Ghraib symbolizes "the failure of a democratic society to investigate well-documented abuses by its soldiers." The documentary record of the abuse has come out in the media in a piecemeal fashion, often lacking context or description. Meanwhile, our representatives in Washington have allowed the facts about what occurred to fester in Pentagon reports without acting on their disturbing conclusions. We believe this extensive, if deeply disturbing, CID archive of photographic evidence belongs in the public record as documentation toward further investigation and accountability.

While we want readers to understand what it is we're presenting, we also want to make clear its limitations. The 279-photo CID timeline and other material obtained by Salon do not include the agency's conclusions about the evidence it gathered. The captions, which Salon has chosen to reproduce almost verbatim (see methodology), contain a significant number of missing names of soldiers and detainees, misspellings and other minor discrepancies; we don't know if the CID addressed these issues in other drafts or documents. Also, the CID materials contain two different forensic reports. The first, completed June 6, 2004, in Tikrit, Iraq, analyzed a seized laptop computer and eight CDs and found 1,325 images and 93 videos of "suspected detainee abuse." The second report, completed a month later in Fort Belvoir, Va., analyzed 12 CDs and found "approximately 280 individual digital photos and 19 digital movies depicting possible detainee abuse." It remains unclear why and how the CID narrowed its set of forensic evidence to the 279 images and 19 videos that we reproduce here.

Although the photos are a disturbing visual account of particular incidents inside Abu Ghraib prison, they should not be viewed as representing the sum total of what occurred. As the Schlesinger report states in its convoluted prose: "We do know that some of the egregious abuses at Abu Ghraib which were not photographed did occur during interrogation sessions and that abuses during interrogation sessions occurred elsewhere." Also, the documentation doesn't include many details about the detainees who were abused and tortured at Abu Ghraib. While the International Committee of the Red Cross report from February 2004 cited military intelligence officers as estimating that "between 70 to 90 percent of persons deprived of their liberty in Iraq had been arrested by mistake," much remains unknown about the detainees abused in the "hard site" where the Army housed violent and dangerous detainees and where much of the abuse took place.

Finally, it's critical to recognize that this set of images from Abu Ghraib is only one snapshot of systematic tactics the United States has used in four-plus years of the global war on terror. There have been many allegations of abuse, torture and other practices that violate international law, from holding prisoners without charging them at Guantánamo Bay and other secretive U.S. military bases and prison facilities around the world to the practice of "rendition," or the transporting of detainees to foreign countries whose regimes use torture, to ongoing human rights violations inside detention facilities in Iraq. Abu Ghraib in fall 2003 may have been its own particular hell, but the variations of individual abuse perpetrated appear to be exceptional in only one way: They were photographed and filmed.
