The reality is that we should be just as concerned by a guy blowing up a truck at the Apple Store as we should about ICE raids at 3 in the morning. With both right wing terrorists and the government, scope creep has a way of ensnaring us all eventually.
Same is true of any terrorist, and any government.
So look, the question is not: Whether or not compromising my personal privacy will bring me more or less security? But rather the question is: Whether or not compromising my personal privacy is consistent with American Ideals?
I say no. So in my personal opinion we, as a nation, have no business mandating that people compromise their personal privacy.
