I was just watching the Bio "Family Secrets" Episode on Demand. I've noticed this before when they show at 0:36 minutes the audio/video footage of the Frank Sr and Jr talking... the Black couple in front of them appear to not be speaking at all or at least the black guy. The black guy also a grin on his face, arms crossed,and by his body language appears as he knows that the room is bugged...I know I sound like some conspiracy theorist,I'm thinking the guy is maybe an agent or I don't know the laws in federal prison but a court wouldn't tell an inmate that the room was bugged ..I mean when making a phone call or sending a letter they tell you that the call is being recorded or the mail may be read but that scene is just weird assuming their agents
