9/11 Co-Conspirators to be tried by Military Commission

Did Obama promise that Gitmo would be shutdown over a year ago? Where is the outrage and demonstrations from left over this policy reversal? These trials are supposed to take place in military tribunals in Gitmo. From Fox News:

A formal announcement is expected by Attorney General Eric Holder later in the day. The decision is a turn-around after Holder said in November 2009 that he had decided the conspirators -- Mohammed, Walid Muhammed Salih Mubarak Bin Attash, Ramzi Bin Al Shibh, Ali Abdul-Aziz Ali and Mustafa Ahmed Al Hawsawi -- should be prosecuted in civilian court. . . .
