This guy is a total fucking douchebag, but I think that’s been covered in this thread.
I do have some thoughts about the editing and the transcript:
At the end, is he really sitting in “open-mouthed silence”, or is he about to speak? The video cuts right when he opens his mouth, and it looks like he could be preparing to utter some racist nonsense. It’s ambiguous as to whether he is unable to give a response (“open-mouthed silence”) or about to give a response (I’m always in “open-mouthed silence” every time I open my mouth in the half-second before I speak). So, do we know if the posted transcript is accurate?
A thought experiment: pretend Hallinan did say something immediately after the moment when the video cuts off, and also pretend that, in the editing booth, it was decided that his bullshit racist rambling after the “like slavery?” question just doesn’t play well, because the filmmakers think (correctly) that it’ll be much more entertaining for the audience to believe that the asshole is dumbfounded by the question, as opposed to trying (although slowly) to respond to it. Would such editing be a breach of journalistic ethics (because it misrepresents what really [hypothetically] happened, à la James O’Keefe), or would it just be good filmmaking (because it’s pretty funny, à la Michael Moore)? Could it be both?
