Also, you would think the McCanns' would want people from their own county analysing the evidence rather then authorities from a foreign country. They already had shown signs of aggravation in the beginning, stating that if it had been a child from their country that went missing, that that child would not receive the same attention.
That shows right there that they are not concerned, and they wanted to easily look for someone to blame, to end the publicity and not give their country a bad name.
When all along, most of the county is probably involved in sex trafficking.
Even the border patrol was involved with sex trafficking in the documentary movie, "HUMAN TRAFFICKING"
