Elysdir writes "The ACLU recently received a "mildly embarrassing" US federal gov't document marked "Secret" (which ACLU says appears to be an overclassification). The gov't has gotten a grand jury to subpoena all copies of the government in the ACLU's possession.
From the ACLU press release:
"If the government can enforce a subpoena in this way, Shapiro explained, 'it could just as easily have subpoenaed the Pentagon Papers from The New York Times and Washington Post. The effect of the subpoena is no different than a prior restraint and it is equally unconstitutional.'""
