You're right, twigs, and I wrote that before hearing on Greta that mamma sloot's visits with Joran were being monitored.
This is pure speculation on my part and I should probably put it in Private Mail to you, but my take is that Mamma Sloot is the dominant parent & spouse. While out of the country, her pathetic head-in-the-sand husband can't even keep his no good son at home the second night of Natalees disappearance!!!
Personally, I think daddy sloot knows his son is neck deep in Natalee's disappearance. He's the nerdy type who has lost complete control of his kid and has thrown his hands in the air. Now, he's just hoping to keep him out of prison for the rest of his life.
Enter momma sloot: The woman gives an Academy Award performance on what a sweet, responsible and great boy Joran is and tells the world that he is also a victim with tears streaming down her face. Too bad her words do not only pass the smell test, they don't even match up with his actions.
If Joran admits to raping her, killing her, and dumping her body in the ocean...he'll probably do about 12 years.
