What would be so wrong about the Smart family benefitting financially from the telling of their own tragic story?
For nine months none of them could concentrate on their careers, and I'm sure they suffered financial losses. Their time and money went into the search for Elizabeth and the efforts to pass the AMBER Alert system. They gave everything they had emotionally, physically and financially to those two causes.
I wish the Smart family well and I would be glad to see them recoup some of their financial losses through book sales and movie revenue. We can't really help them personally, but we can allow them that much without looking down on them.
