"The Founders also gave Americans the Fourth Amendment to the U.S. Constitution because they understood that defending individual privacy against the grasp of government authority is an essential human right as well as an important safeguard of freedom.

Snowden may have broken the law, but so did the Founding Fathers when they issued that famous declaration 237 years ago. They did so in defiance of a powerful empire, just as Snowden did. The world is better off that they chose to defy the laws of their time, and Snowden's idealistic act may leave us better off too. I suspect Thomas Jefferson, James Madison, and the rest of those revolutionaries might have understood."
