W. Kamau Bell returns to "Salon Talks" to discuss his Showtime documentary series, "We Need to Talk About Cosby." The show takes a full look at Bill Cosby as a comedian and pioneering figure in Black culture and weaves in how his downfall, personally and publically, forever changed his legacy. Bell tells Salon's D. Watkins that Cosby challenges the question "Can we separate the art from the artist?" in the biggest ways. Bell explains why he dove into the project and why the process was scary, at times.
