Doesn't anyone have decent recording software? I took my studio apart and sold my stuff. But there are a lot of things that can be discerned by scrubbing and filtering audio.
I understand your point. I was thinking more along the lines of this video not proving much even if that lone voice had shouted the slur.
One voice does not a “chorus” make, and there have been no other recordings, as far as I know, that show anything remotely substantiating the accusations made by those “esteemed public servants and gentlemen”.
