Clearly as the risk increases, for example for a public figure who chairs a "standards and conduct" committee, then the level of security, or mistrust, should increase - perhaps to the level of not using them.
Agree, 100%
Whilst we all have something to lose, for sure these girls would be doing this day in day out with Joe Soap, and I am sure that they haven't spilt the beans on him, as no one is interested, blab that you are a big shot, and chair a standards and ethics committee, and surprise, surprise, someone is interested in tripping you up! He wanted the trappings of being Big-Wig, and with that, comes responsibilities, he was to dumb, or arrogant to appreciate that fact, and so was caught with his trousers down.
Lessons to be learned for all of us for sure, but I would and do still trust WG'd more that most politicians!
