What if any of them had a child that had spent the night with little Danielle and instead of Danielle being abducted, it was their child.
Perhaps these hypothetical parents knew Brenda through Girls Scouts and thought the house was a safe one.
If they learned that the VDs may well be "swingers", how many do you think would be willing to stand on their opinion that the lifestyle wasn't relevant?
How many would be satisfied if LE looked right past it and didn't delve into it deeper? Would they want to know every detail of that night and the identities of each person who visited the home? Would they closely question the timeline? How content would they be with accepting only Damon's story of what happened in the earlier part of the evening?
You get the picture. They would be clamoring for all these answers and much more. Why should it be any different because the child just happens to have lived in the home? Heaven knows we have seen plenty of parents who harm their own. These questions are valid ones and it is unfair to Danielle for them not to be asked.
