Well I think the obvious answer to that is :It doesn?t matter. Since when did the government base their constraints off of what we believe to be moral and virtuous? Of course, I would say that it is morally wrong for them to invade our privacy. But, now, if it were for our own safety, does that make the morality slightly skewed? Therein lies the ambiguity.
I believe that there should be some fixed height of shady activity that, once passed, requires Big Brother to step in for a constant bird?s eye view. That way Colonel So-and-so can?t just read your love letters for personal ?jollies?.
Nobody likes the idea that the government can and will read their private documents or interactions online; but really what can we do about it? Nothing, we have no control over the power of the government, as bad as it sounds. I believe we should just cope with the unnervind uncertainty for now, becuase some day it might turn into some communist internet dictatorship and then we will be pleased to have this situation back.
However bad something sounds, it could always get worse. And according to Murphy's Law, "What ever could go wrong, will."
