The decision by the European Court of Human Rights last week to refuse to block the extradition of the radical Muslim cleric Abu Hamza al-Masri and four others to the United States on terrorism charges removes one of the last external checks on our emerging gulag state.

Masri and the four others, all held in British jails, will soon join hundreds of other Muslims tried in Article III federal courts in the United States over the last decade. Fair trials are unlikely. A disturbing pattern of gross infringements on basic civil liberties, put in place in the name of national security, has poisoned our legal system. These infringements include intrusive surveillance, vague material support charges, the use of prolonged pretrial solitary confinement, classified evidence that the accused cannot review, and the use of political activities, normally protected under the First Amendment, to demonstrate mind-set and intent. Muslims caught up in the Article III courts are denied the opportunity to confront their accusers and to have their religious and political associations protected, and they rarely find a judge courageous enough to protect their rights. These violations of fundamental civil liberties will not, in the end, be reserved exclusively for Muslims once the corporate state feels under siege. What is happening to them will happen to the rest of us.

“One of the misapprehensions of the last decade is that the government had to go outside the law to places like Guantanamo or Bagram to abridge the rights of suspects in the name of national security,” said Jeanne Theoharis, a professor of political science at Brooklyn College who has been an outspoken critic of the rights abridgement occurring in Article III courts. “But this is not the case. A similar degradation of rights that has characterized the prison at Guantanamo has also affected the judicial system within the United States. The right to dissent, the right to see the evidence against you, the right to due process, the right to fair and speedy trial, the right to have a judge who will be impartial, the right to fair and not disproportionate punishment, and the right not to be punished before you are convicted have been taken from us in the name of national security. It is not just in special secret prisons that this occurs, but also — dismayingly — within the U.S. federal courts.”

This is not about the guilt or innocence of Masri, an Egyptian who lost an eye and a hand as a mujahedeen fighting in Central Asia and who has repeatedly called for violence against the United States and allegedly helped orchestrate violence. This is about the right of all accused to a fair defense and humane detention conditions. Once Masri arrives on U.S. soil he will receive neither. He will, even before he is tried or convicted, endure prison conditions that replicate the brutality suffered by those in our offshore penal colonies, including the one at Guantanamo Bay. He will enter a world of prolonged and psychologically crippling isolation, made worse by the likely application of so-called special administrative measures. He will spend his days in a tiny cell under constant electronic surveillance. At New York’s Metropolitan Correction Center, where Masri and the other men will most likely first be incarcerated, he will never be allowed outdoors. He will be permitted to spend only one hour a day outside his cell, alone in a cage. Masri and the four other suspects could spend years in these conditions before trial. Because of security restrictions, it will take as long as six months for letters from his family to reach him. His lawyers can be prosecuted if they repeat in public what he tells them, especially about the conditions of his incarceration.

And, once he goes on trial, he will be in an Article III court, where national security provisions will almost certainly guarantee his conviction. Once convicted, he and the others are likely to be sent to the federal Administrative Maximum facility (known as ADX), in Florence, Colo., to spend, potentially, a lifetime in solitary confinement. There he will be permitted, at most, an hour a day out of his cell, in a cramped cage nicknamed “the dog run” because it looks like a dog kennel. His meals will be delivered to his cell through a slot. He will not be permitted to work in prison industries or have congregational prayer, an essential tenet of the Muslim faith.

“Torture is legal in the United States in the form of years of solitary confinement and the use of special administrative measures,” Theoharis said when we spoke by phone. “The Obama administration has not only refused to hold Bush officials accountable for torture, but maintains torturous conditions in federal prisons. And the Obama administration willfully misled the European Court about the conditions these prisoners face.”

Nearly every state now has a “supermax” prison similar to the federal prison at Florence, which former ADX Warden Robert Hood once called “a clean version of hell.” These prisons presage a dystopian world where disobedient citizens are seized, stripped of rights and broken psychologically. Law professor Laura Rovner and Theoharis — who is an outspoken advocate for her former student Fahad Hashmi, being held in the Florence supermax — detailed the corrosion of justice within federal courts in an article in the American University Law Review. They noted that the distortion within the federal legal system “represents a particular way of seeing the Constitution, of constructing the landscape as a murky terrain of lurking enemies where rights must have substantial limits and the courts must be steadfast against such dangers.” The two professors went on to argue that while legal scholars and human rights advocates have examined the dangers of these paradigms in Guantanamo, they have generally failed to acknowledge that “the federal system is similarly infected by such paradigms.”There are currently an estimated 25,000 prisoners imprisoned in supermax facilities. They are disproportionately Muslims and people of color. Many, including Hashmi, Dritan Duka, Oussama Kassir and Seifullah Chapman, were not found by the courts to be involved in specific terrorist plots but instead were incarcerated under these conditions for their “material support” to terrorism. The prisons are equipped with special housing units for those who do not show a proper deference to authority. These “H-units” hold prisoners under special administration measures, or SAMs. They live in cells of only 75 to 85 square feet. They endure almost complete social isolation and sensory deprivation as well as round-the-clock electronic surveillance. And it is in these units that even the most resilient are psychologically destroyed.

Prolonged isolation, says Craig Haney, a psychologist at the University of California at Santa Cruz who has studied the effects of solitary confinement, eventually induces “appetite and sleep disturbances, anxiety, panic, rage, loss of control, paranoia, hallucinations and self-mutilations” as well as “cognitive dysfunction … hopelessness, a sense of emotional breakdown … and suicidal ideation and behavior.” Haney found that “many of the negative effects of solitary confinement are analogous to the acute reactions suffered by torture and trauma victims.”

Masri, a burly man who once was a bouncer in a nightclub, is accused of 11 terrorism charges, including attempting to set up a terrorism training camp in a remote area of Oregon and involvement in a kidnapping in Yemen in 1999 in which three British tourists were killed. He was based at north London’s Finsbury Park mosque, which I visited several times when I was covering al-Qaida for The New York Times. His rhetoric was always incendiary and conspiratorial, assuring him press coverage, which I suspected he coveted. He called the 9/11 attacks a Jewish plot and the Columbia space shuttle explosion “punishment from God.” Richard Reid, the hapless shoe bomber, whose past associations I was investigating in London, attended the mosque. Masri was never an important Muslim leader in Britain or abroad. He made headlines mostly because he sought them. He was jailed last year in Britain on charges of soliciting murder and inciting racial hatred. And at that point the U.S. began the process of extradition.

Masri faces the possibility of life imprisonment. He will be extradited with four others, including Khaled al-Fawwaz, a Saudi national, and Adel Abdul Bary, another Egyptian. These two men are accused of having been aides to Osama bin Laden in London and allegedly taking part in the 1998 U.S. embassy bombings in East Africa in which more than 200 people were killed and thousands injured. Babar Ahmad, a British citizen in detention since 2004, will also be extradited. He, along with Talha Ahsan, is accused of using his now-closed website, Azzam.com, to support terrorism. Ahmad has been held in custody in Britain without trial for nearly eight years.

The ruling of the European Court of Human Rights, handed down Sept. 24 after the men requested that the court block their extradition, in essence certifies that U.S. prison standards are compatible with European human rights. This opens the door for any European nation receiving extradition requests from the U.S. to swiftly turn prisoners over to U.S. authorities. The ruling came despite the fact that 26 human rights groups including the ACLU, the Center for Constitutional Rights, and Human Rights First supported the prisoners’ contention that they would be housed in inhuman conditions in the United States. The human rights groups predicted that the court’s ruling would have “serious implications … for legitimizing the use of conditions of confinement that violate human rights.”
