Is this the best defense of the actions of NSA employees publicly available? He spends a lot of time denying pervasive surveillance puts us in a panopticon where the FBI and other LEAs can observe everything we do. And never mentions parallel construction once. He tries to justify a Cold War sized, and then some, security state by invoking North Korea. This is a big bowl of very weak sauce. The director's standard of…
But it plausibly is just what a purports to be - a portrait of the mentality of a rank and file NSA employee (I don't see any evidence that he's even "mid-ranking" if "mid" means middle management). That mentality seems to be a fusion of "surveillance doesn't matter if you have nothing to hide" and "America is under siege".
The thing is, it is good that the NSA has a lot of sincere employees are not now simply there for the power. It seems like this means instances of surveillance abuse are only period rather than constant. This puts them above the level of local police, who tend to have a fair of "ex-high school bullies and wanna be bullies". Yes, that's good but given the NSA's unchecked power, if an "institutional drift" towards the cynical use of power began in earnest, there isn't much people could do legally to stop that. And that is very bad.
