Difficult to straddle that one, ain't it.
The competing domains of public security and privacy divide folks who otherwise may seem to share values.
Clearly some targetted spying is going to be necessary.
But removing privacy from the whole world in order to protect a microscopic number of American lives does cross the line by just a speck.
By microscopic, I exclude major al qaeda terrorist events as they fall within a probable cause orbit for surveillance.
We spy on you to protect you is so Orwellian it is scary.
