US intel chief James Clapper: I didn't lie about spying program, just gave "erroneous" answer

It’s almost as if the timing of the leaks is intentional to allow for the government to admit they do x, but deny they do y, only to have the next leak force them to retract their claim that, “alright, we’re doing y, but there’s definitely no way we’re doing z, no siree…” …and so on and so forth.
It seems to be quite effective in enhancing the distrust both from the people and from foreign governments, which seemed to be Snowden’s intent. I can’t decide if he deserves credit for planning that, or if it’s just coincidental.
