It is nothing of the sort. Please, do not use a legal term to describe the content of your video, as (a) you know not what it means; and (b) the content of your video is not, by any stretch of the imagination, "proof beyond a reasonable doubt" of anything.
Also, I notice that you continuously call the content of your video "testimony" and I notice that you repeatedly try to frame the content of your video in a manner suggestive of legal constructs. You do know, do you not, that in legal terms, "testimony" is evidence given under oath? There is nothing in your video to suggest that the interviewees were under oath.
It appears as though you are trying very hard to lend your video some semblance of credibility by deliberately framing your descriptions of it in terms that you know full well are inapplicable - because you realize that it has no credibility with respect to the premises upon which it was based.
I understand how difficult it must be for you to accept that not even your fellow conspiracy theory believers accept your video as even remotely compelling evidence of anything, but does that not give you pause to re-think things and consider that you just may be dead wrong? If not, it should. I mean, if even the diehard, heavy gauge tinfoil members of your group don't buy it... well...
