"If one accepts that all 18 on the "confirmed" list have returned to the battlefield, that would be 4 percent of the detainees who have been released, Bergen said.
Bergen also noted Federal Bureau of Justice Statistics data that show the recidivism rate for U.S. state prisoners who have been released is more than 65 percent. Those same numbers show that about half of the released prisoners are returned to prison.
Bergen said that some of the prisoners at Guantanamo may not have been terrorists at all but were singled out by vengeful villagers who told U.S. authorities they were al Qaeda.
"We know that a lot of people who were in Guantanamo don't qualify as being the 'worst of the worst,'" he said, quoting former Defense Secretary Donald Rumsfeld's assessment.
Bergen said some of those "suspected" to have returned to terrorism are so categorized because they publicly made anti-American statements, "something that's not surprising if you've been locked up in a U.S. prison camp for several years."

So this is what we are going to do.. We are going to hold some indefinitely because we cant prove they partook in terrorist activities, but we got a "hunch"? Talk about a bitch slap in the face of "justice".
You also never answered my questions; So if they are terrorists why cant anyone charge them? Why are they cleared to be released?
