More info to provide you a bit of context: Renita Chaney Hill was 15 years old when the four year "relationship" started. Cosby flew her to meet with him in various cities and kept in touch with her parents, asking them about her grades in school.
She was more than old enough to realize what was going on. Unless her parents were total idiots, they knew what was going on. Pretty girls do not fly around the country to meet with actors in their hotel at night because the actor wants to ‘mentor’ them.
YGBSM! Folks might try reading about the Rat Pack to get an idea of what was considered normal sexual mores in Hollywood 30-40 years ago. Even now...would YOU allow a pretty daughter to fly across the country and meet with an actor in his hotel room at night, alone?
