None of the politicians can really stop this surveillance state. If some politician had the courage to stop it and then some terrorist incident, however minor, were to happen, the opposing party would absolutely crucify him. They all know this. This is why both parties are behaving in the same way.
Something really scary happened on 9/11. The politicians promised security in exchange for freedom and people happily agreed. Nothing new there at all. The difference was that this time around, computer technology allowed the creation of a perfect police state. All police states in the past have had a fundamental problem; a society can support only so many secret policemen. Not enough secret policemen to create the perfect police state. With computer technology, that limit is erased. I am afraid this is going to become quite dystopian.
