Obama has become such a laughing-stock. Does anyone seriously believe that Putin and the KGB do not spy on Russians?
The KGB are now called FSB. They have internal jurisdiction much like FBI and MI5.http://en.wikipedia.org/wiki/Federal_Security_Service_(Russia
Here's a link to an excellent award winning film, "Lives of Others" 2006 which covered the Stasi in East Germany before unification.http://en.wikipedia.org/wiki/The_Lives_of_Others
I believe both the FSB and the FBI conduct surveillance on both criminal cases and on political cases when directed.
The NSA gathers the entire "haystack" on the assumption they need it in order to surveil the needle.
What is new is that it is all out in the open presumably. If the USA does it, presumably the UK and maybe others can either do it too, or get info from us.
The need is based on 9/11/2001 mistakes. If you believe the security services of the US can and do prevent terrorist crimes, using such capabilities, then meddling about to restrict their capabilities carries the risk of letting a terrorist act proceed, instead of stopping it.
If you believe this or other administrations would abuse this data, for political or any reason, then it needs at the vey least tremendous oversight.
