The Associated Press reports that the Obama administration is seriously considering transferring all of the detainees at Guantanamo Bay in Cuba to a joint prison/courtroom complex in the United States and a Michigan prison in Standish is one of the two sites being strongly considered for the location.

The Obama administration is looking at creating a courtroom-within-a-prison complex in the U.S. to house suspected terrorists, combining military and civilian detention facilities at a single maximum-security prison.

Several senior U.S. officials said the administration is eyeing a soon-to-be-shuttered state maximum security prison in Michigan and the 134-year-old military penitentiary at Fort Leavenworth, Kan., as possible locations for a heavily guarded site to hold the 229 suspected al-Qaida, Taliban and foreign fighters now jailed at the Guantanamo Bay detention camp in Cuba.

Such a plan has been endorsed in the past by Rep. Bart Stupak, in whose congressional district the prison is located, Sen. Carl Levin and former Gov. John Engler; it’s been opposed by Rep. Pete Hoekstra, Republican candidate for governor in 2010. The Standish prison is slated to close soon due to budget cuts.

The plan, according to AP, is to have a single prison overseen by the Department of Justice, the Department of Homeland Security and the military. The inmates would then be segregated and overseen by one of those departments depending on how they are going to be tried:

The Justice Department has identified between 60 and 80 who could be prosecuted, either in military or federal criminal courts. The Pentagon would oversee the detainees who would face trial in military tribunals. The Bureau of Prisons, an arm of the Justice Department, would manage defendants in federal courts.

A courtroom complex would be built inside the prison for both the civilian and military trials. The most controversial element of the plan, however, would be the plan to build “long-term holding cells for a small but still undetermined number of detainees who will not face trial because intelligence and counterterror officials conclude they are too dangerous to risk being freed.” That’s something that civil liberties groups are adamantly opposed to, arguing that if you cannot convict someone in court you must let them go.
