governed by strict rules, etc
A few comments here, and indeed the actual speech that is referred to in the article, make it seem like this snooping is happening despite the law.
If Snowden's revelations on the NSA have taught us two things it was 1) that we were indeed being snooped upon in vast numbers with means and processes that go way beyond what a judge would issue a warrant for, and 2) that it is all perfectly legal.
So, the fact that some government official promises to play by the rules is doubly insulting since a) it suggests that said official could not play by the rules and b) is demonstrating how much of an idiot said official is taking us for by making us think that such words actually hold a promise.
Sorry, government official, but it is your sworn duty to play by the rules since you took office. Playing by the rules is a given that should not even be worthy of mention.
So, promising to play by the rules just means "we promise to keep on doing what we're doing right now" since that is exactly what they're already doing.
The issue at hand is that more and more _citizens_ are rising against these rules and for the respect of their private lives. It's a good thing J Edgar Hoover is dead, otherwise said individuals would all be summarily carted off to Guantanamo under the label "Dirty Commie Terrrist".
