I don't doubt for a minute that Precious THOUGHT she'd be rolling in dough after she got through setting these 'white boys' up.
I think Gottlieb's descriptions might have been written for Crystal.
He could show them to her with a claim of showing her the "original descriptions" she gave to refresh her memory.
I think the argument was that the cry of rape was a spur of the moment thing to get out of involunatry commitment. But like any con artist on the make, when she saw Nifong was going to run with this and people started telling her should could sue these guys, it was in her interest then to pick 3 guys from pretty wealthy families.
Fortunately for the US justice system and unfortunately for Nifong, Mangum picking people with enough money to fight back was not in Nifong's interest. I do agree Mangum did not do any research, but I bet someone did.
