Who airbrushes out the face of the interviewer?

Inquiring minds want to know why the "film-makers' obscured the face of the primary antagonist/interrogator, and why these 'plain students' refused to answer where they were student?.

No legit academic or journalistic aspirant would CAMOUFLAGE their affiliations. They'd be proud of it, would flaunt it. "Hello Congressman. I'm Woody, in a class at GWU. We're doing a project. Would you mind answering a couple of quick questions?"

This smacks of another thuggish, Andrew--asswhole-Breitbart, ACORN-entrapment stunt.

If such pasty-faced little gunsels had accosted me in like manner, one of 'em would have gone home with my pointy-toed boot up his ass.
