This manual, which was attached to an email from the latest AntiSec release, has no listed author and little indications as to its source. The introduction states that information in the document “was collected and interpreted by multiple agencies” and the manual is intended for use only by “public safety agencies”. However, a 2003 article from a local newspaper in Colorado indicates that the manual was produced by an unknown U.S. Government agency and is used by Joint Terrorism Task Forces to teach local police about “criminal protest tactics”. According to an email in the most recent AntiSec release, the manual is still being circulated today in relation to police confrontations with Occupy protests. For more information, see our accompanying article about the document and its history.
