I think Binney quit in 2001.
The interviews and videos were put together by Still I think starting in June 2014. In some interviews Binney mentions the Bush admin (while he was working at NSA) and in other interviews he references the Obama admin and their ongoing snooping (and possible targeting of tea party sympathizers).
It was unclear to me in which year(s) he was being threatened with prosecution. I assume more recent years as I don’t think he came forward publically until after the Snowden affair. I could be wrong about that, however.
Perhaps Still will put together a timeline of these events.
Thanks, I agree with your assessment...NSA was bad under Bush but even worse under Obama.
