http://www.sourcewatch.org/wiki.phtml?titl..."The Freedom of Information Act applies to "agency" records. Contractors, in this context, are not "agencies," even where they perform decisional roles. Similarly, government officials are subject to a body of conflict of interest provisions, pay caps, limits on political activity, and labor rules that do not similarly constrain contractors who perform similar, even the same, work."
* "In April <2002>, the Army told Congress that its best guess was that the Army had between 124,000 and 605,000 service contract workers. In October, the Army announced that it would permit contractors to compete for "non-core" positions held by 154,910 civilian workers (more than half of the Army's civilian workforce) and 58,727 military personnel." <12>
