I just had a crazy idea. I think it was Kim who told the security guard that Crystal was drunk. When the guard calls 911, she does not know what color Kim's car is, she has to ask Kim. So the the guard must not have gone out to see Crystal. So the guard's opinion of Crystal's condition must have come from Kim.
Kim is telling the security guard what to say. You can hear Kim in the background of the 911 call.
Personally, I don't believe for a second that Kim tried to find out where the AV lived.
Remember, Kim seems to have been recruited by Simeon. What was Simeon's angle? Willie Gary? Jesse Jackson? Civil Lawsuit. What was the environment at that time?
1). There was no monetary value in saying it didn't happen and Kim would have been villified in the black community. More than villified. Remember the environment at the time - Black Panters, Jesse Jackson, Victoria Peterson.
2) Some in Durham like Kim's lawyer believed there was potentially a civil lawsuit or maybe a large settlement to make it go away. Kim doesn't need much convincing to be on the side of Green.
Actions speak louder than words. Kim's actions that night show, IMO, she was not concerned about Crystal. It does show she was concerned with getting her out of her car and getting out of Dodge.
In short, Crystal became a celebrity and a cause in the weeks after the party and Kim's only opportunity to benefit personally was to get on that bandwagon.
We need to examine those radio tranmissions closely and compare them with times. The nurse at Durham access describes Crystal as being INCOHERENT - So how does she convey the information on her kids? That is the question.
