MI5 feared GCHQ went 'too far' over phone and internet monitoring | UK news | The Observer - 0 views

Senior figures inside British intelligence have been alarmed by GCHQ's secret decision to tap into transatlantic cables in order to engage in the bulk interception of phone calls and internet traffic.According to one source who has been directly involved in GCHQ operations, concerns were expressed when the project was being discussed internally in 2008: "We felt we were starting to overstep the mark with some of it. People from MI5 were complaining that they were going too far from a civil liberties perspective … We all had reservations about it, because we all thought: 'If this was used against us, we wouldn't stand a chance'."The Guardian revealed on Friday that GCHQ has placed more than 200 probes on transatlantic cables and is processing 600m "telephone events" a day as well as up to 39m gigabytes of internet traffic. Using a programme codenamed Tempora, it can store and analyse voice recordings, the content of emails, entries on Facebook, the use of websites as well as the "metadata" which records who has contacted who. The programme is shared with GCHQ's American partner, the National Security Agency.

Interviews with the UK source and the NSA whistleblower Edward Snowden raise questions about whether the programme:■ Exploits existing law which was passed by parliament without any anticipation that it would be used for this purpose.■ For the first time allows GCHQ to process bulk internal UK traffic which is routed overseas via these cables.■ Allows the NSA to engage in bulk intercepts of internal US traffic which would be forbidden in its own territory.■ Functions with no effective oversight.

The source claimed that even the conventional warrant system has been distorted – whereas police used to ask for a warrant before intercepting a target's communications, they will now ask GCHQ to intercept the target's communications and then use that information to seek a warrant.There is a particular concern that the programme allows GCHQ to break the boundary which stopped it engaging in the bulk interception of internal UK communications. The Ripa requirement that one end of a communication must be outside the UK was a significant restriction when it was applied to phone calls using satellites, but it is no longer effective in the world of fibre-optic cables. "The point is that this is an island," the source said. "Everything comes and goes – nearly everything – down fibre-optic cables. You make a mobile phone call, it goes to a mast and then down into a fibre-optic cable, under the ground and away. And even if the call is UK to UK, it's very likely – because of the way the system is structured – to go out of the UK and come back in through these fibre-optic channels."
