I doubt he knows anything that KSM hasn't already given up.
That's not the point. On the other hand, if Moussaui rats on his buddies (i.e. confirming KSM's intel), then we've got a public example of an OBL crony getting turned rather than dying for his cause.
"I doubt he knows anything that KSM hasn't already given up."
Yeah, but the govt. didn't tell us everything KSM told them.
If not so that means our brilliant interrogators when told by KSM that Moussaoui was for a second wave, didn't ask him what the second wave was.
