How did she know he worked for NSA? Did she have any way to verify he was an American or worked for the NSA? Do you think the NSA hires people who specialize in HUMINT? Why would he tell her he works for the NSA?
Too many unanswered questions. It's more likely she made it up because it gets people angry and that's what activists need to do.
If you have problems with other parts of our government, by all means criticize them and be an activist. Speak your mind and vote. Making up stuff about the NSA is intellectually lazy.
