The recent revelations over NSA phone record surveillance has brought the issue of government spying, privacy and transparency back into the spotlight - but not for the first time. U.S. history shows repeated collisions between government's desire for information and a citizen's right to privacy, and between the government's freedom to act and the public's demand for transparency.
We take a historical look at transparency and privacy in American government, from the Nixon days of wiretapping to Obama's gathering of cell phone data. We examine how U.S. law has changed over time to accommodate shifting technologies, and we look at shifting perceptions of government surveillance. [via @MPR and @MPRnews]
