If you missed the Edward Snowden interview what you should know is he tried to use proper whistle-blower channels to get the word out about the US population being spied upon. This has been confirmed in fact by NBC News. He was generally told to shut up and it was explained to him he better not go public with the information he had.
Moreover, he went on to say that virtually all electronics can be turned into a microphone remotely and other truly scary things to anyone who takes their freedom and civil liberties seriously.
One other point is he says he was at a much higher position in our intelligence services than the government and president has told us. Take a look and decide for yourself who you believe is more trustworthy.
