Wish I had the original recording myself so I could drag it through processing. "Coons" is what I heard, and you're right: the audio STINKS. However, there may be more than one segment/recording/source we are all arguing about. Apparently there's a lot of audio on this out there, but my guess is we're not hearing all of it on a regular basis.
Then you have the problem that both sides try this stuff in the public arena, which complicates it all. Think it best to wait to the trial, to be sure... even that might be a big "maybe."
