I have a few recordings that I have posted before of Billy and his shenanigans on 7.255/3.840. I have overheard him singing, playing music (or doing both at the same time Karaoke style), jamming and being malicious.
Billy has the same thought process as Baxter when it comes to doing whatever he wants, thinking he's in the right and how the FCC is going to lose because they have no case. So because he works in law and has attorney 'skills', he has the overconfidence of a Chihuahua in the face of a rabid "Pit Bull" known as the FCC.
I haven't heard him say anything racial (per se), but that doesn't mean he hasn't said it. I just have yet to catch him in the act of doing it and have it down on video as proof.
