On the one hand, yes, I believe that sensationalism, scare tactics, and manufactured outrage rule the day in the media (outside of any kind of political bias). When it comes right down to it, they're competing for eyeballs, and they'll do whatever it takes to get them.

But on the other hand... to blame Nancy Grace for Duckett's suicide--which genuinely seemed like what the AP writer was trying to do--seems off to me, in a post hoc ergo propter hoc kind of way. I would wager that it was something Duckett had been considering before the interview, and that it was because she had something to do with her son's disappearance (despite those quotes from her friends and neighbors). Just my inkling.
