The dynamic on domestic spying is simple. You're not being spied on. And even if you are, it's only to protect your children from being killed. And we know you are not doing anything wrong, so you have nothing to worry about.
And it works. Americans as a whole don't care if their phones and emails are tapped by the NSA so long as the NSA doesn't go crack addict with their credit card numbers or tell their spouses about all that porn.
