The "I have nothing to hide" defense is one of the most ridiculous things I've ever heard. Seriously, when the police haul you off, do you think the "I didn't think it was bad" defense is going to hold up?
The government decides who it will arrest and for what reasons. Talk about blowing up the White House, get arrested. Talk about doing harm to US politicans, get hauled off. Eventually they'll take you away for just making stupid anti-Bush jokes over the phone if someone doesn't stop this.
Look, as a member of the US military, I don't believe in dropping our guard or banning wiretapping, but there are more sensible measures we can take to ensure security.
1) Secure the southern border. Build a wall, deploy the National Guard from all the border states, tell Mexico to close the border to all but commercial trade, whatever. We're so exposed at the border that I'm more worried about terrorists slipping in through there than at JFK or LAX. Speaking of...
2) Sensible airport security. Patting down 85 year old ladies in wheelchairs isn't security, it's stupidity. Having people take off all of their shoes/belts/anything with a zipper isn't security, it's insanity. Yes, metal objects should come out of pockets, and your backpacks should go through a screener, but it's just gotten ridiculous.
3) If we have to wiretap, go through FISA. Seriously, it exists for a reason. We can wiretap 100% legally, if we only took the time to go through the court systems. Reagan said nothing in a democracy should ever be done in secret, and I 150% agree with that, especially when it comes to home defense.
