Wikileaks has, over the past three years, published a variety of sensitive documents, ranging from the American military’s manual for operating its prison in Guantánamo Bay to evidence of corruption in Kenya and the dumping of toxic chemicals off the coast of Africa. It also published a list of Web sites that the Australian government proposed blocking, the extreme-right British National Party’s membership roll, an analysis of a major Icelandic bank’s default risk, and video footage of a US helicopter attack in Baghdad that killed 12 people, including a Reuters journalist and photographer.
