Tell that to a country that has had a military coup, or similar. One day the military obeys civilian orders, the next day they don't. Same could happen with NSA. One day they obey the law, the next day they don't.
Wouldn't have to be the whole agency, just some small, but connected, group. They could sell information to foreign countries or, maybe more likely, companies or do all sorts of other socially destructive but personally profitable things.
Of course it doesn't literally happen overnight. But would we know about it if NSA/CIA and similar started going rogue? Seems to me that the government would cover up any extra-legal activities that were discovered so we'd never know until it was too late.
