I disagree, 100%. The NSA is far more powerful, and far - FAR - more dangerous now than the FBI ever was under Hoover.
If you don't think this is the case, I don't think you're really looking honestly at the situation. In the Hoover/FBI days, we had a chance - the Operation Snow Whites' and so on. Now, however, there is no such chance: the NSA has far, far too many safe-guards in place to protect itself, and has infiltrated - and controls, directly - too many so-called 'peace movements' and other groups that might have a chance at awakening the sheeple. We must be more diligent, and with greater resolve to fight back now, than ever before in history - because we are at the cusp of allowing a seriously evil influence over the world to have its will - whereas in the 60's and 70's, people were willing to stand up and fight, now hardly anyone will. At all.
Back in the worst days with Hoover they were actively targeting specific political activists and basically running black ops against them. We haven't reached that stage with NSA, as far as I can tell, though the potential is certainly there.
Maybe you misinterpreted what I said, it shouldn't be an excuse to wait until things get worse before taking action. The fact that the potential is there should be enough.
We HAVE reached that stage, and worse. The NSA - and other spook agencies - are actively engaged in warfare with various social/peacenik groups, and has been demonstrated time and again as a constant source of infiltration, provocation, and so on. Agent-Provocateur isn't just the name of a knicker factory - its a real tactic deployed against enemies of the regime, which include civic groups (unions), churches and other citizen organizations.
We simply cannot have this power out there, in the hands of these people.
Nothing happened, the programs continued, the people running it back then are now happily retired or left the world without a mark on their record. There were no mass firings of the hundreds of agents directly implicated in these obviously unethical and illegal things.
The people running COINTELPRO back then to find the communists tutored the government agents that are now trawling through the massive NSA data to find terrorists. The capabilities were only expanded.
