Nancy Grace lets her emotions run over her too often (her husband was murdered). But, she's a woman, and it's practically impossible for women to keep their emotions in check anyway.
Did you hear about that one woman she interviewed who killed herself afterward?
Apparently this woman's son had been kidnapped or lost or something and Nancy was grilling the mom-- asking her why she left the kid unsupervised or whatever. Then a few days later the woman killed herself....
