The recidivism rate among former Guantánamo Bay detainees is lower than was previously believed, according to the latest reports. The director of national intelligence released new data Monday showing that fewer than 16 percent of detainees released from the detention center reengaged in terrorist activities. About 12 percent more former detainees, a total of about 72 people, are under observation on the suspicion that they may reinvolve themselves in terrorist groups. The confusion over a higher rate of reengagement stems from a February report released by congressional Republicans that conflated the two numbers, arriving at a 27 percent rate. According to the new report, former captives released in countries that are considered unstable seem to have a higher likelihood of rejoining terrorist groups like al Qaeda.
