> So tell me Dave,
I think this is a question of ignorance on their part. They don't understand that it is not possible to have a secure conversation with your bank while not being able to have a secure conversation with other people. They don't understand that having a back door that GCHQ can open means that every other government around the world and half the criminal gangs too can also open at will.
The whole political class just doesn't seem to have the faintest clue about how technology works and they seem to be determined to listen to "advisers" who will tell them what they want to hear. This week it might be Dave, in a few weeks it might be Ed or Nigel or Nick, they all seem to act in the same way once they get a whiff of power.
