huge dog

ガーディアン紙は英情報機関、政府通信本部（ＧＣＨＱ）が欧州、北米間にある２００本以上の通信ケーブルに傍受装置を取り付け、「テンポラ」と名づけられた通信傍受オペレーションのもと、電話の盗聴や電子メール閲覧などを大規模に行っていると報じました。
最後でスノーデン氏は「大がかりな犬を飼っている」と言っていますが、これは傍受装置（surveillance　sytem）を、クンクンと情報を嗅ぎ回る（scoop up）犬にたとえた隠語的な言い回しでしょうか。
いずれにしても米中会談をねらって中国側が仕掛けたといわれる情報リーク。彼の処遇に注目が集まります。（UG）

GCHQ taps fibre-optic cables for secret access to world's communications

Britain's spy agency GCHQ has secretly gained access to the network of cables which carry the world's phone calls and internet traffic and has started to process vast streams of sensitive personal information which it is sharing with its American partner, the National Security Agency (NSA).

The sheer scale of the agency's ambition is reflected in the titles of its two principal components: Mastering the Internet and Global Telecoms Exploitation, aimed at scooping up as much online and telephone traffic as possible. This is all being carried out without any form of public acknowledgement or debate.

One key innovation has been GCHQ's ability to tap into and store huge volumes of data drawn from fibre-optic cables for up to 30 days so that it can be sifted and analysed. That operation, codenamed Tempora, has been running for some 18 months.

GCHQ and the NSA are consequently able to access and process vast quantities of communications between entirely innocent people, as well as targeted suspects.

This includes recordings of phone calls, the content of email messages, entries on Facebook and the history of any internet user's access to websites – all of which is deemed legal, even though the warrant system was supposed to limit interception to a specified range of targets.

The existence of the programme has been disclosed in documents shown to the Guardian by the NSA whistleblower Edward Snowden as part of his attempt to expose what he has called "the largest programme of suspicionless surveillance in human history".

"It's not just a US problem. The UK has a huge dog in this fight," Snowden told the Guardian. "They [GCHQ] are worse than the US."
