WASHINGTON — It is the other Guantánamo, an archipelago of federal prisons that stretches across the country, hidden away on back roads. Today, it houses far more men convicted in terrorism cases than the shrunken population of the prison in Cuba that has generated so much debate.
An aggressive prosecution strategy, aimed at prevention as much as punishment, has sent away scores of people. They serve long sentences, often in restrictive, Muslim-majority units, under intensive monitoring by prison officers. Their world is spare.
Among them is Ismail Royer, serving 20 years for helping friends go to an extremist training camp in Pakistan.
In recent weeks, Congress has reignited an old debate, with some arguing that only military justice is appropriate for terrorist suspects. But military tribunals have proved excruciatingly slow and imprisonment at Guantánamo hugely costly — $800,000 per inmate a year, compared with $25,000 in federal prison.
The criminal justice system, meanwhile, has absorbed the surge of terrorism cases since 2001 without calamity, and without the international criticism that Guantánamo has attracted for holding prisoners without trial.
