Prosecutor Says Sept. 11 Suspects Can Be Held Past War Crimes Sentence

Regardless of the outcome of their someday trial, the men accused of plotting the attacks of Sept. 11, 2001, can be held forever as prisoners in the war against terrorism in a form of preventive detention, a military prosecutor told the presiding judge on Wednesday.

Defense lawyers were asking the judge to rule that, if convicted, Mustafa al-Hawsawi, one of the suspects in plotting the attack, would have any sentence to a term of confinement reduced by the number of days he was held by the United States before trial. He has been held since 2003.

The argument, in a pretrial hearing in the decade-old Sept. 11 case, was the latest installment over a long-running, unresolved question of whether a prisoner, once he completes a war crimes sentence, is entitled to release from military detention.

Col. Joshua S. Bearden, an Army prosecutor, said the answer was no. He urged the judge to reject the request as both premature, because the government is seeking the death penalty in the case, and beyond the scope of his authority.

No date has been set for the start of the trial of the four men accused of conspiring in the commercial airliner hijackings that killed nearly 3,000 people on Sept. 11, 2001.

Mr. Hawsawi has been held for the past 20 years but not as punishment or exclusively for trial, Colonel Bearden said. The prosecutor said the charges against Mr. Hawsawi were separate from the detention that keeps him “off the battlefield” in the U.S. war with Al Qaeda.
