Fighting terror with more information is a problem?

I have no problem with the news sites recommending stories to me, or the shopping sites figuring I’m good for another look at those size-41 shoes. I have no problem with someone using my supposedly “private” information to sell me more and target me for whatever they know I’m interested in. But I have to draw the line.

And isn’t the right place to draw the line with the guys who want to use that information to fight terrorism and save our lives?

The NSA. I don’t mind if (fill in the blank) is keeping an eye on me, but turning information over to the government to fight terrorism? How dare they...
