HOW MUCH does the government know about you?

According to the NSA, they’re already tracking/plan to track information like internet searches, emails sent and received, websites visited, blogging activity (including posts you read and comment on), social media activity, photos viewed online, videos watched, phone call records, video calls, online purchases, legal documents, financial information, travel documents, educational records, DNA, facial recognition, cable TV shows watched and recorded, health records, and more.

Perhaps a little more than Google, Facebook, and most commercial businesses. Who learned from whom?
