I think it just comes down to the trade off of freedom vs. loss of life.
I mean that's what it's really about, isn't it? We are giving up the freedom of privacy for the potential of more security?
Yet, This is not the American Way
At one point we realized that in order to protect the freedoms of our people we had to die. That's why so many fought in the revolutionary war. To protect our rights and freedoms as citizens against the State (England, at the time).
If we just lay down like dogs now and let our government walk over us like dogs, all those lives will have been wasted.
