There's no question that the single most dramatic step taken by Barack Obama since his inauguration on Tuesday was the series of executive orders banning use of torture by federal agencies (including the CIA), eliminating the CIA's secret "black sites," and setting into motion the eliimination of the Gitmo prison and the legal limbo it represents.

Michael Isikoff and Mark Hosenball have a good summary of the orders at Newsweek, along with an account of the internal debate that led up to it. And Marc Ambinder of The Atlantic explains some of the "hard cases"--particularly Yemeni and Chinese prisoners--that will complicate the closure of Gitmo.

If you actually want to read the four executive orders involved, Salon has usefully posted them here.
