It shows she's a real person and not just a coached actor paid to lie about fraud. This is important since it drives holes through people just lying about shit. It shows she's a real person from the community and is genuine.

She's not the best speaker, but you also have to realize that she was under pressure from three extremely hostile people sitting in leather chairs that stared at her with utter disdain and hatred. You'd fuck up a bit too knowing the whole world is looking at you on top of being towered over by people that hate you for telling the truth.

I liked that her ghetto came out a bit. She's not an intellectual that is always proper. She's from the city. And she doesn't take shit. She's real and she's not making shit up. It actually adds to her credibility.
