From American Civil Liberties Union:
In June 2011, the ACLU filed suit against the State Department to enforce a FOIA request seeking 23 embassy cables previously disclosed by WikiLeaks. The agency released redacted versions of 11 and withheld the other 12 in full.
The five excerpts [here] show the government’s selective and self-serving decisions to withhold information. Because the leaked versions of these cables have already been widely distributed, the redacted releases provide unique insight into the government’s selective decisions to hide information from the American public.
