Cohen is so stupid, he thinks repeating this over and over will make it true.
I'm sure that some of the students did not know that morning that she had been murdered and completely disposed of. ALE did not know they had a murder case that morning. If the students had know that on the morning of their departure, would the Government of Aruba have refunded their plane tickets, paid for hotel rooms and meals for all 125 of them for weeks, phoned their parents in Alabama to tell them their kids would be kept in Aruba for weeks or months while Aruba leisurely investigated Natalee's murder? I think not.
Correction: That should have read, "I'm sure that some of the students did not know that morning that she was missing. None of the students knew that she had been murdered and completely disposed of."
