Binney
Walter Binney served the NSA for over 30 years faithfully. Ironically, a special task force raids his location with guns drawn as he has become a whistleblower exposing the truth of the NSA illegally spying on citizens.
Presidential Policy Directive 20
The NSA officials tell the public that they lack a policy framework for cyber watching. Ironically, the policy currently exists as they deny it to the public. It's called Presidential Policy Directive 20.
Poitras
Poitras believes that Citizenfour has chosen her specifically for this project. However, ironically, he says that she selected herself as she has been subject to detention by the U.S. intelligence agencies for making a film on the Iraq War. She's experienced the harassment Snowden seeks to stop.
Keith Alexander
The NSA Director says that the agency has not been intercepting any online communications of U.S. citizens. Ironically, this is after Snowden has already said that the NSA has been doing it for years.
Phone
Snowden is hyper paranoid about protecting himself from the NSA finding him. Ironically, he forgets to unplug the phone in his hotel room which he knows has a computer chip in it that will allow the NSA to listen in to the room.
