美国土安全部公布网络敏感词

The Department of Homeland Security has been forced to release a list of keywords and phrases it uses to monitor social networking sites and online media for signs of terrorist or other threats against the US.

美国国土安全部近日应要求公开了用于监控社交网站和网络媒体的“敏感词”，这些“敏感词”用于防范针对美国的恐怖分子和其他威胁。

The intriguing¹（有趣的） the list includes obvious choices such as 'attack', 'Al Qaeda', 'terrorism' and 'dirty bomb' alongside dozens of seemingly innocent words like 'pork', 'cloud', 'team' and 'Mexico'.

Released under a freedom of information request, the information sheds new light on how government analysts² are instructed to patrol the internet searching for domestic and external threats.

The words are included in the department's 2011 'Analyst's Desktop³ Binder⁴' used by workers at their National Operations Center which instructs workers to identify 'media reports that reflect adversely⁵ on DHS and response activities'.

Department chiefs were forced to release the manual following a House hearing over documents obtained through a Freedom of Information Act lawsuit⁶ which revealed how analysts monitor social networks and media organisations for comments that 'reflect adversely' on the government.

However they insisted the practice was aimed not at policing the internet for disparaging⁷ remarks about the government and signs of general dissent⁸, but to provide awareness⁹ of any potential threats.

As well as terrorism, analysts are instructed to search for evidence of unfolding natural disasters, public health threats and serious crimes such as mall/school shootings, major drug busts¹⁰, illegal immigrant busts.

The list has been posted online by the Electronic Privacy Information Center - a privacy watchdog group who filed a request under the Freedom of Information Act before suing to obtain the release of the documents.
