I agree with you RGVTx. I don't doubt Dave's motives at all. He's a kind and gentle man who is looking for answers. He more than gave Aruba the benefit of the doubt for the longest time of any of them. I believe that he has every right to expose the horrific corruption that he has seen surrounding his daughter's case and the mental torture that they have been and still are being, put through. I sincerely believe he would not produce a book to profit for himself. He wants, just like Beth, to bring Natalee's body home, and put her to rest.
And I agree w/you and RGVTx. There is NO questions when it comes to Dave's motives.
I think papa sloot will buy the book hoping he can sue Dave; and Dave hoping he will so he can get papa in court any way he can, IMO. Dave is a kind and gentle man w/extreme patience.
