Incarceration in America is a failure by almost any measure. But what if the prisons could be turned inside out, with convicts released into society under constant electronic surveillance? Radical though it may seem, early experiments suggest that such a science-fiction scenario might cut crime, reduce costs, and even prove more just.

Former AT&T engineer Mark Klein handed a sheaf of papers in January 2006 to lawyers at the Electronic Frontier Foundation, providing smoking-gun evidence that the National Security Agency, with the cooperation of AT&T, was illegally sucking up American citizens’ internet usage and funneling it into a database.

The documents became the heart of civil liberties lawsuits against the government and AT&T. But Congress, including then-Sen. Barack Obama (D-Illinois), voted in July 2008 to override the rights of American citizens to petition for a redress of grievances.

Congress passed a law that absolved AT&T of any legal liability for cooperating with the warrantless spying. The bill, signed quickly into law by President George W. Bush, also largely legalized the government’s secret domestic-wiretapping program.

Obama pledged to revisit and roll back those increased powers if he became president. But, he did not.

Mark Klein faded into history without a single congressional committee asking him to testify. And with that, the government won the battle to turn the net into a permanent spying apparatus immune to oversight from the nation’s courts.
