Of course not. Unless this someone affirms he/she can do better.
Then this someone could be asked to provide proof about his/her statements, be it video, witnessess, personal interaction, etc., you know... the usual means for proving claims.
For the "someone" in question there have been numerous witnesses and ample opportunities for personal interaction.
There are plenty of people with video out who get questioned regularly - it doesn't seem to provide any real level of "proof".
And if you could actually learn much from the videos then we wouldn't need all these discussions, right? There's plenty of video available on people with good stuff.
OTOH, another "someone" (but not the "someone" in question) once advised me - what ever you do, don't put up any video of yourself, it just stirs up the peanut gallery.
