In the latest revelation of how the federal government is monitoring social media and online news outlets, the Electronic Privacy Information Center has posted online a 2011 Department of Homeland Security manual that includes hundreds of key words and search terms used to detect possible terrorism, unfolding natural disasters and public health threats. The center, a privacy watchdog group, filed a Freedom of Information Act request and then sued to obtain the release of the documents.
The 39-page “Analyst’s Desktop Binder” used by the department’s National Operations Center includes no-brainer words like “”attack,” “epidemic” and “Al Qaeda” (with various spellings). But the list also includes words that can be interpreted as either menacing or innocent depending on the context, such as “exercise,” “drill,” “wave,” “initiative,” “relief” and “organization.”
These terms and others are “broad, vague and ambiguous” and include “vast amounts of First Amendment protected speech that is entirely unrelated to the Department of Homeland Security mission to protect the public against terrorism and disasters,” stated the Electronic Privacy Information Center in letter to the House Homeland Security Subcommittee on Counterterrorism and Intelligence.
