Or the people with whom you share a social graph. The friend of yours that's also friends with a known local drug dealer who in turn just happens to have cartel connections, even though you had no idea and have never even experimented with legal pharmaceuticals. Or the aunt that was once a part of a political rally that showed real possibility of overthrowing the government. Or the brother that's showing signs of mental instability on social media that everyone has missed - "he was such a good kid, none of us saw it coming." but the data predicted it; and that innocent vacation your family took to Egypt last year, a once in a lifetime opportunity to see the Giza plateau suddenly looks a whole lot more sinister - suddenly your whole family is questioned as being terrorists and the witch hunt has begun. You lose your business, your jobs, the community you loved. Even the most innocent of data can be misconstrued and turned against you.
