I have obtained an Information Bulletin that originated in the Threat Management Division (TMD) of the Federal Protective Service (FPS) at the US Department of Homeland Security (DHS.) I have posted the whole bulletin online here and also embedded it at the bottom of this post. The bulletin is unclassified but For Official Use Only (FOUO.)
The information bulletin number is FPS HQ IB-006-2014.
Here’s the overview section:
Anonymous is calling for a “Nationwide Day of Rage” on Thursday, August 21. The demonstrations are
purported to protest the death of Mike Brown in Ferguson, MO, and subsequent police actions. Currently, there
is no information to indicate there will be civil disobedience at these protests.
From the details section:
Information has been received from various law enforcement sources, other federal agencies as well as open
source outlets indicating Anonymous has issued a call to action, calling for a “Nationwide Day of Rage” on
Thursday, August 21.
Anonymous is an asymmetric associated international network of hacktivist and activists entities known for a series of distributed denial-of-service (DDoS) attacks on government, religious and corporate websites as well
as with individuals associated with the group wearing Guy Fawkes masks. Anonymous members have
garnered law enforcement attention for activities targeted against US government agencies, media, military
contractors, military personnel and police officers.
The demonstrations are purported to protest the death of Mike Brown in Ferguson, MO, the subsequent police
actions against protesters in the city as well as in support of the demonstrators demanding the prosecution of the
identified police officer.
Currently there is no indication that protests are expected to become violent. However, recent protests in
Ferguson have resulted in violence, property damage and subsequent arrests.
