I agree with you, but I was responding to the claim:

"b/c it has nothing to do with an investigation...now blackmail and extortion???"

I read that as something stronger than "we need to take lessons from history." I think the statement goes further than that to claim that the NSA's purported justifications are entirely pretense and the real motivation is blackmail and extortion. That I think requires stronger proof than "someone sometime did something."
