Answer 1

I've seen "Obsession"
http://www.obsessionthemovie.com/
It uses the technique of presenting a statement from an expert and then immediately proving the statement with a video clip of an event.

Also uses the technique of not proving the opposite view. Could be there is no proof of an opposing view, or that the film-makers are purposely keeping quiet about evidence which doesn't motivate the viewer to their cause. Audience doesn't know unless they do some research.
