Frightening claims are being made that U.S. prisons are breeding grounds for Islamic terrorism. The premise is that the dangerous and unstable people who populate prisons can all too easily be swept into radical religion and terrorism. A 17-person blue-ribbon task force, assembled by researchers from George Washington University and the University of Virginia Medical School, issued a report in 2006 that concluded that because Islam feeds on bitterness and alienation (now ubiquitous in American prisons) the United States "is at risk of facing the sort of homegrown terrorism currently plaguing other countries." Ian Cuthbertson, the director of the Counterterrorism Program at the World Policy Institute, makes similar claims, calling prisons an ideal place for recruitment into jihadist organizations. Just as prisons are "schools for crime," he says, in which petty offenders "graduate" into more serious criminal careers, so too our prisons have become "universities" for advanced training in terrorism.

Based on recent field research, including extensive interviews of inmates and prison staff in state and federal prisons, I have come to a far less pessimistic assessment. My research, conducted with Obie Clayton of Morehouse College, involved visits to 27 prisons in nine jurisdictions. In total, we interviewed 200 prison officials and 270 inmates. Our central finding is that the rate of prisoner radicalization is not just low but falling. Those on the inside--inmates, line correctional officers, intelligence officers, and senior administrators--consistently report that not only is inmate radicalization far below the alarmists' claims, but barely a trace can be found.

The primary reason is the increased safety and order in U.S. prisons. As Anne Piehl and I reported last spring in THE WEEKLY STANDARD (see "The Other Big Crime Drop" in the April 28, 2008 issue), the quadrupling of the prison population over the past 30 years has been associated with increased safety and security behind bars. Across a wide set of measures, U.S. corrections has become safer and more orderly. For example, in 1972, there were over 90 prison riots. By 2005, prison riots had become rare, almost to the point of disappearing. The prison homicide rate is now lower than the homicide rate for the U.S. population. (This lower prison homicide rate exists before adjusting for demographics, not to mention criminality.) Prisons have become zones of safety--not the dangerous snake pits that New York Times crime reporter Fox Butterfield has portrayed as close cousins to the abuses uncovered in the Iraqi prison of Abu Ghraib.

Prisoner radicalization is like any other challenge to corrections officials, from gangs and crowding to high rates of inmate violence and inmate suicide. These are problems to be attacked and solved, rather than inevitable or overwhelming circumstances.

The Pennsylvania Department of Corrections, for example, stresses down to the lowest staff levels the importance of watching for signs of radicalization and reporting them up the chain of command. A central office collects and collates this information, and ensures the flow of information to and from external law enforcement. We interviewed inmates in the state's two toughest high security prisons and one medium security prison. (The two high security facilities were largely out of control a decade ago; both are now relatively safe and orderly.) No signs of Islamic radicalization appeared in any of the three prisons. The greater order achieved during the prison buildup, moreover, would allow officials to quickly see, and do something about, any signs of radicalization.
