Is Carl Clark really an intelligence community whistle-blower? He seems to have done one media interview and then disappeared. If I hadn’t experienced a lot of what he describes, and known many others who have also, I would think it might be a hoax. see: http://www.freedomfchs.com/cclarkintrvw.pdf
To me it seems that stopping these sort of unofficial covert actions against citizens is far more important than whether we have our metadata logged by PRISM.
The latter is officially sanctioned, at least in the US, and may soon be here too. What trouble can they cause us with that, even reading our emails etc would not be a problem if the information was only used for security purposes.
What Carl Clark describes though are methods that, while they may be necessary tricks of the trade for agents operating in very difficult circumstances against legitimate targets, can also be turned to target citizens for other reasons: political, personal and even psychopathic.
I think we need more focus on ways to make sure this unofficial abuse of power can’t continue, whether that abuse is from within intelligence organisations, discreetly outsourced or proliferating to who knows where.
