It depends how unreasonable you want to be about what counts as proof. Do you want to be as absurd as the OJ Jury and dismiss DNA evidence?

Remains of 9/11 hijackers identified
Forensic experts in New York say they have identified body parts of two of the 10 hijackers who flew planes into the World Trade Center on 11 September 2001.

Ellen Borakove, a spokeswoman for the New York Medical Examiner's Office, said the identifications had been made using DNA samples provided by the Federal Bureau of Investigation (FBI).

The FBI had collected the DNA from tiny traces of skin on the steering wheels of vehicles hired by the hijackers and from hair samples recovered from their hotel rooms.

Earlier this month, the FBI provided profiles of all 10 hijackers, including alleged ringleader Mohammed Atta, so their remains could be separated from those of victims.

"No names were attached to those profiles. We matched them, and we have matched two of those profiles to remains that we have," Ms Borakove said.

Fact is, the hijackers had motive and opportunity and some of their remains have been identified. We see some of them going through the airport on the video just released. Denying that Arabs were on the planes depends on you continuing to dismiss evidence. There should be some internal logic applied to this case. We even have an audio tape of Mohammed Atta as he is hijacking the plane. By our absurd level of proof, nothing could ever be proven.
