It's free publicity and a dose of notoriety - those are important reagents of modern media alchemy!
These kinds of assumptions are Nancy Grace's trademark. If there's ever been a truly ugly individual, she is it. And I don't mean physically ugly - which she also qualifies but, the deep-seated ugliness that comes from her crass, obnoxious, convict-and-get-the-facts-later personality.
I stopped watching her when I was going to college, but about 6-8 weeks ago I was changing channels and saw her discussing something/someone I agreed with her. However, her abrasive style, loud voice and constant interruptions reminded me of the old Nancy Grace that originally alienated me, prompting me to change the channel, notwithstanding the slight headache she gave me.
Grace also noted that "Melinda committed suicide before that interview ever aired."
Melinda knew that her interview was going to be aired, so why would Melinda need to watch it when she already knew that Nancy made her look guilty, with no sensitivity for her feelings or her state of mind? As for Nancy, who assumes the worst in so many individuals, it's very telling that she casts herself above her guilty until proved innocent TV persona.
Take responsibility, Nancy, and admit that your aggressive interview was most likely a trigger for this woman's suicide. You will sleep better... that is, if you have a conscience.
