I don't know anything like enough about either telecoms or OSs to be of any value to the spooks, but I think my response would be to appear suitably cowed, and work quite diligently, but you know, I find it remarkably common that I make mistakes when under pressure. It is just so easy to put a semicolon in the wrong place or forget the braces around a code block - or even put them on the wrong lines.
When the data inadvertently gets leaked all over the place I'd obviously be greatly upset and immediately offer to put things right, but I guess I'd be dismissed for incompetence. Shame that.
P.S. I had to make several edits of this little bit of text!
