US spy chief Clapper defends Prism and phone surveillance

[Peter Lemkin]

Another lie exposed.

Allegedly your mobile can be located even when it's turned off.

Yes. I don't even know now if taking your battery and SIM card out will work. There was a recent murder case here in Melbourne. The woman was missing and they traced her phone movements and collected the CCTV footage from the route and matched it with a suspect. His mobile phone matched the same route at the same times. In this case it was good police work but we know they are doing this all the time.

A rare example of this being used to solve a crime, rather than create one by illegal spying. I do believe removing the battery and SIM card would prevent tracking/listening in. In order to get some response from a phone when the battery is removed they must supply some energy via a beam of some kind and frequency....thus, would not be used for general surveillance - but for specific surveillance, IMO....as this is very intensive targeting and hard work for people, not computers alone. Don't think they YET have such a general system set up for this via automated systems, with the exception of collection devices that are able to detect any mobile phone that passes by it - with or without a battery - [many of these are mounted now in cities along busy roads, in shopping areas, city centers, etc.] Big Brother welcomes you and watches your every move!
