Per FOX news:

The Pentagon said Tuesday it has fingerprints, DNA, photos or reliable intelligence to link 27 detainees to the battlefields since their release from the prison on Guantanamo Bay, Cuba.

That’s about 5 percent of the 540 terror suspects released from the prison. Another 9 percent of freed Guantanamo detainees are suspected to have rejoined the terror activity. That’s 74 detainees in all.

"What this tells us is, at the end of the day, there are individuals, that if released, will again return to terrorist activities," Pentagon spokesman Bryan Whitman said Tuesday.

Both President Obama and President Bush have made it clear that they intend to detain in perpetuity (without trial if need be) anyone who poses a risk to the U.S. So, it’s inappropriate to claim that the Gitmo almuni that Bush freed have "rejoined" terrorist activity.

It is however quite rational to conclude that at least 14% of Gitmo’s nonterrorist guests convert to terrorism during their stay. And, who wouldn’t?
