Snoden is nothing but a TRAITOR. Why? Having exposed US secrets, he then tried to hide in China and Russia - fact. He will now likely get protection in a tin-pot dictator state, as neither China or Russia will touch him (a smart decision).
These surveillance systems are in place not to read your trivial emails or catch you downloading porn, but to assist in the prevention of acts of terrorism and provide evidence in other significant crimes (perhaps such as child porn, money laundering etc). People who whine about potentially being snooped are either being foolishly anarchist or have something to hide.
Sonden has forever damaged the governments ability to protect the innocent and prosecute the guilty. As the old saying goes, if you have nothing to hide....
I look forward to Snoden's body washing up on a beach somewhere, and the sooner the better. A true WORM of a character who is NOT a hero by any measure (unless you are Al-Qaeda or Taliban).
Do NOT worship anyone who removes the protection of the innocent. I would give up absolute privacy for a safer country any day. Period.
