If you lose your laptop or smartphone, you're losing an awful lot of deeply personal data with it. That point's underscored by the current case of David Miranda, the partner of Guardian journalist Glenn Greenwald, the reporter who is responsible for breaking the lion's share of news from the Edward Snowden NSA revelations. British authorities detained Miranda and took several of his devices. The British government says what they did was allowed under anti-terror laws. But the search has been heavily criticized as overreaching. Security consultant Ashkan Soltani says the Miranda case is a reminder of just how much of our lives our devices can hold.
