Well, even a "tabloid" story can have value; it's all in
how it's covered. For example, even the Paris case is interesting in a way... just not the way the masses tend to gobble it up.
You were right about Greta. Disappointing too, because I think she's intelligent, but she seems to become obsessed. Case in point, the Laci Peterson case; she covered it virtually non-stop from day 1 through the husband's conviction. Just Van Susteren's coverage drove me away from the case altogether.
Then, a few nights ago while covering the Kelsey Smith story, Van Susteren was talking with Smith's parents as they held a memorial 'celebration'. She asked a few questions about Smith, then she asked the father something like, "So this guy Edwin Hall... what a monster he is, huh?" There was a pause and the mother answered, "We'd really like to keep our focus on remembering Kelsey tonight." So Greta said, "I'll take that cue to close out."
