Notice that she only talks about certain kinds of crimes but never where the perpetrators are of a protected minority and the victim is white. They do happen but you would never know that from watching Nancy Grace.
The exception was Jodie Arias. The victim was the white Morman scrunched in the shower with his throat slit, numerous slash wounds, and gunshot.
That is the only “sensational” horror where I followed Nancy’s program with regularity, and a couple of others that led and followed her show.
I had not watched Nancy before, or since, but during the Arias stuff, Nancy was fine.
