WASHINGTON (Reuters) - President Barack Obama said in an interview aired on Monday he worried that detainees freed from the U.S. military prison at Guantanamo, Cuba, might resume attacks on the United States.
But he told NBC News that closure of the prison was a matter of upholding U.S. values and law, and that a failure to do so would ultimately make Americans less secure.
"Can we guarantee that they're not going to try to participate in another attack? No," Obama said. "But what I can guarantee is that if we don't uphold our Constitution and our values, that over time that will make us less safe. And that will be a recruitment tool for organizations like al-Qaeda."

That's rich. See, the Constitution is only relevant when it is convenient for the administration. And in this case it is really NOT relevant for his reasoning. By any stretch of the imagination or wrodsmithing, the detainees in "Gitmo" are NOT US cirtizens and do NOT fall under purview of the Constitution.
