thats the mindset of most people I've talked to about the nsa, "if i'm not doing anything wrong then they can spy on me all they want"

Well, 2 things to consider:  Do you value privacy?  If not, then would you hand over your emails & passwords to complete strangers?  I doubt it.

Secondly, do you value how your tax dollars are spent?  Do you really like the idea of busting you butt, only to have billions of tax dollars spent to monitor your every waking moment and piece of communication?  I doubt it!
