There is an article in The Guardian by Paddy Ashdown that falls at the first fence… i.e the tagline at the very top…
NSA surveillance: who watches the watchers? It’s not the widening of state intrusion that’s wrong, but the weakening of the safeguards that should be there to protect us
No that is the key error. It is not the lack of safeguard that is the issue, it is the huge amount of power in the hands of the state. It is indeed the widening of state intrusion that is wrong because there are simply no ‘safeguards’ that can stop the abuse of that amount of power by whoever currently controls the political process.
As has been said before, this is not a “left vs. right” issue, it is a “top vs. bottom” issue. NO ONE and NO INSTITUTION can be trusted with that kind of power. Ashdown is one of the people at the top, there is simply no way for him to understand.
