“But I am very concerned about them spying on American citizens.”
Exactly right. NSA has the mission of spying on everyone but Americans. Their lying about spying on Americans - either directly, or indirectly through “agreements” with other countries is particularly disturbing.
What this will do is galvanize countries to control their own communications infrastructure. Smart ones will do just that. Things will be less interconnected, and US firms will lose business as it becomes clear they are for the most part paid informants to the NSA.
I have to believe that some of the largest internet companies, and indeed, the growth strategy and architecture of the internet itself was directed to benefit surveillance.
Government can never control itself, and never will.
So to add to your point, yes, I’m very concerned about the spying on American citizens. I’m more concerned with how they were comfortable lying about it. I’m even further concerned by the lack of consequences for their admitted lying about it.
Why is Clapper not behind bars, for instance?
No doubt, NSA is involved in political activities. No doubt they have the ability to impact politics - and since government cannot restrain itself, no doubt they’ve used it.
So who goes to jail for this?
Not to worry (/sarc). Candidate ∅™ promised in 2007 it would never happen :
"I will never spy on the American public unless they are suspected in a crime".
