This is exactly the sort of argument that I really dislike. A still from a video that makes someone look bad and therefore proves they are evil.
The Free Karen Read followers of Turtleboy do this on social media a lot. Posting weird pictures of the Alberts and McCabes (but usually only the women) that make perfectly normal looking people look ugly. And the anti-KR folks do this to Karen and her family.
I honestly don't see the point. In the end it's the facts of the trial that should matter and whether the commonwealth has proved their case beyond a reasonable doubt.
Who care if Karen Read scribbles on a legal pad or makes funny faces or gets upset while watching her trial?
