As President Obama awaits formal recommendations this month on issues surrounding the U.S. military prison at Guantanamo Bay, Cuba, it is crucial that policymakers and the public have an accurate picture of the threat to the United States posed by those detainees already released.

Contrary to recent assertions that one in seven, or 14 percent, of the former prisoners had "returned to the battlefield," our analysis of Pentagon reports, news stories and other public records indicates that the number who were confirmed or suspected to be involved in anti-U.S. violence is closer to one in 25, or 4 percent.

It was already well over 90 degrees and there was no breeze whatsoever. We were soaking in our shirts just standing there, which makes what I began to see that much harder to imagine.
