Michael Isikoff (who allong with John Barry wrote the recently retracted Newseek story) appeared in an interview on MPS yesterday. While acknowledging a "mistake," he basically made the case that the tremendous secrecy surrounding Abu Ghraib and other prisons makes it virtually impossible for the public to get any information about what its government is doing. This is an excellent point. Future history books will marvel at the U.S. public's willingness to give its government a carte blanche to set up secret incarceration centers around the world where people are held incognito.
As for blaming Isikoff for the riots, it's ridiculous. Why not blame the administration responsible for setting up the situation (Abu Ghraib and the nebulous "war on terror")?
