Don't you think she was letting the guy just make a fool of himself? She's trying to show folks like you that these guys exist.
I agree with your take on it--she was letting them show themselves for what they are.
That said, I rarely watch Greta. She has such a stiff mouth, with a jutting jaw, and an immobile upper lip, she looks like a puppet when she talks. Not to mention I didn't care for her on CNN during the Klaus Von Bulow trial.
Although lately she has gotten some good information out about Terri Schindler Schiavo...
That's what I thought. I've seen Greta with similar people who've made my jaw drop, but Greta just keeps moving on.
I think she's giving the audience the opportunity to see these people for the jerks they are. You don't need any editorializing from Greta to know that someone who says that the pictures of the two suspects 'look Jewish' is a complete idiot.
