Wouldn't it be easier to use some kind of case or pocket [0] that acts as a Faraday cage? 0: http://www.popsci.com/sites/popsci.com/files/styles/large_1x_/publ

  That seems safer, with Snowden's device it has to detect transmission after it begins to occur in order to trigger shutdown or alert the user, so it's going to leak some amount of RF even if little. A properly constructed Faraday cage shouldn't though.

    I think that Snowden's device would play a different role, I was comparing it to removing the main and backup batteries.

  So it records and transmits later, at opportunity.

    Good point. I guess it depends on the use case.
