You'd think that but that's not actually true. Google's infrastructure is way too big to be completely secure. There are several ways to penetrate Google's network.

I know some of the people in the security team and they are pretty good, but arrogance will be their undoing.

Google has an internal team called the Orange Team that performs security audits and, so far, they have always been successful in penetrating Google's network. If they can, what makes you think the NSA hasn't done that already?
