Yes the NSA takes privacy very seriously. The NSA spies on everyone else but doesn't spy on Americans, period. Oh, well yeah of course we collect data from Americans but if we find out we are looking at an American's data we're supposed to throw it away immediately.
Throw in a harmless joke about "big scary NSA" to lighten the mood. Nice salary, nice benefits. Most of the students ask for applications after class, it's a career forum for area studies majors and this is by far the most lucrative job presented in the semester.
It's honestly pretty easy to make a deal with the devil, especially if you're smart enough to argue that he's not the devil.
