Gotta keep in mind though, that the first shot you can't really see what the woman is doing, and for the second woman, you don't know what she does when she goes out of frame. If the dude releases an unedited version, then it should clear up some doubts that people still have.
Having said that, I do believe that the guy actually saw what he was filming, its just that he does a poor job of showing it on video. And people should definitely have to show their faces at security, regardless of immigration (scared of being racist is not an excuse... Islam is not a race!)
