Data released Tuesday suggests that an additional 9 percent of freed Guantanamo detainees are suspected to have rejoined what the Pentagon defines as terrorist activity.
In all, 74 of approximately 540 detainees that have been released have either returned or are believed to have returned to the fight.
The Pentagon says it has fingerprints, DNA, photos or reliable intelligence to link 27 detainees to the war since their release. Some constitutional lawyers have disputed the data because it is not specific about the evidence used to track the detainees.
