They just had on some American "legal experts", all three of whom practically hooted at the idea that the parents' lawsuit would have the slightest chance of succeeding. Whether in Aruba or in the states, they all said no way.
Fox News just reporting that all evidence taken from sloot home will be tested in Holland not in Quantico.
Also, the FBI was never allowed inside that house only outside.
I think the parents have bought into a legal eagle or two telling them they can work this thing to get info and resolve the case. Not likely. We keep thinking we can use USA muscle in foreign countries. Doesn't happen.
It may not "succeed" in the traditional sense, but it emphasizes their resolve to pursue every avenue and keep the pressure on.
