I am still searching for news about the military brigade that President Bush has deployed inside the U.S. I set up a Google Alert so that I would see any news article published.
This morning I see that three days ago the American Civil Liberties Union filed this request under the Freedom of Information Act. The complete article, together with the PDF file of the entire request, can be found on the ACLU website here. The following is quoted from their summary.
Posse Comitatus Act - FOIA Request (10/21/2008)
Description: The American Civil Liberties Union demanded information from the government about reports that an active military unit has been deployed inside the U.S. to help with "civil unrest" and "crowd control" – matters traditionally handled by civilian authorities. This deployment jeopardizes the longstanding separation between civilian and military government, and the public has a right to know where and why the unit has been deployed.
