(NEWSER) – US prisons are capable of taking on all 166 Guantanamo Bay detainees, thereby allowing the US to close the facility, a report finds. "This report demonstrates that if the political will exists, we could finally close Guantanamo without imperiling our national security," says Sen. Dianne Feinstein, who commissioned the report in 2008. Indeed, 98 prisons across the US already hold terror convicts, the Government Accountability Office report says.
