I'm more and more convinced NBC knew all about Rob's past and then set it all up, which on top of being sleazy, is puts them at fault for putting all the girls at risk.
They are either criminally negligent in NOT finding out about the assault, or at fault for knowingly endangering all the girls. Either way, they can be sued for not screening out a known danger to the girls safety, and for providing him with alcohol.
Additionally, it may have been an illegal game show if they consulted with contestants about decisions on who to keep. Think back to Quiz Show. You can't determine the outcome and then steer the show that way. There are laws.
Am I paraniod? Or just annoyed?
Damn, and to think this used to be fun...
