The word “goon” has multiple meanings as I’m sure you know. It can go all the way from goofy to a mobster to a troublemaker or creep. I haven’t heard the entire audio although whenever it has been played, I have never heard the word either “goon” or “coon.” I’m not saying you didn’t hear it but that I didn’t. I don’t watch Anderson Cooper.
I heard it while watching a video clip. I don’t watch AC either. They named their audio expert so I was at least inclined to believe him, though who knows.
