In other news: according to this Reuters article, a US appeals court declined to hold Rumsfeld and his henchmen responsible for Gitmo:
A U.S. appeals court ruled on Friday that four former Guantanamo prisoners, all British citizens, have no right to sue top Pentagon officials and military officers for torture, abuse and violations of their religious rights. [...] The men claimed they were subjected to various forms of torture, harassed as they practiced their religion and forced to shave their religious beards. In one instance, a guard threw a Koran in a toilet bucket, according to the lawsuit.
Interestingly, Reuters even notes the anniversary ("The decision by a three-judge panel to dismiss the lawsuit came exactly six years after the first detainees arrived at the U.S. military prison at Guantanamo Bay in Cuba.") and mentions the demonstrations.
None of that would have happened without the ACLU's campaign.
