US cites national security threat from secrets - FoxNews.com: "The U.S. government asked a judge Thursday to order the return of a secret document about a detention center in Afghanistan that it mistakenly gave to a civil rights group, saying its release could frustrate military and intelligence-gathering efforts and do serious damage to national security, including interfering with foreign diplomatic relations."

It sounds like they have a really low bar for "serious damage to national security"
