I think that the last section is the most convincingly argued by far. You address many of the problems that come with using videos for evidence, namely the lack of context, poor views and only one perspective, and you give concrete examples to back this up. I know that we're all short on time, but if this is something that really interests you, I'd recommend expanding this one section and giving a bit more in-depth analysis as opposed to trying to touch on so many issues (perhaps post finals). I'd definitely read it.
