I simply don't trust any government with any more power than absolutely necessary. On any given day, I'm at very little risk from a hypothetical terrorist; while "my" government seems to be doing it's best to make my life less convenient and waste my time/money. Have you gone through an airport lately?

If a terrorist really wants to do something, they will figure out how to get it done with or without skype; we just don't need any more security theater. IMO, we have already gone well over the line in the interest of providing the illusion of security to the masses.

Let's all understand that there will be more terrorist attacks against americans in our lifetimes, just like their will be more plane crashes, more auto accidents, and more earthquakes and floods. There will also be more random street crime, and people will continue to die from treatable illnesses. We do not have a "cost is no object" approach to any of those threats, but we still have our collective panties in a twist over terrorism. Time to move on.
