You really do not understand the American court system. This case has been working its way through the system for a number of years. The traitor Snowden (who now works for your beloved Soviet Union (formerly known as Russia)) was NOT the key to this.
The fact that the court ruled that the NSA had over stepped and acted illegally has to do with what the NSA did NOT what Snowden did
How many were prosecuted and went to federal prison for this blatant betrayal of criminal activity?
