I still suspect that there were two tapes out there (at least) -- ABC had one, decided to dub the tape and cut the last 15 minutes, and give the dub one to the CIA. Another media outlet had been given the tape and also turned it over to the CIA. The CIA notices that the ABC tape is 15 minutes short -- that's why it was the FEDS reporting it rather than some ABC mole.
On the video, the unknown man's face is masked with a Palestinian scarf and sunglasses. He stabs the air with his finger, which appears to be fair-skinned, as he delivers his warning in American-accented English.
"Allah willing, the streets of America will run red with blood, matching drop for drop the blood of America's victims," says the speaker, who calls himself Azzam al Amriki (or Azzam the American). "What took place on September 11th was but the opening salvo in the global war on America."
The next attacks, he adds, "could come at any moment."

The tape, delivered to ABC in Islamabad last Sunday by a courier who was paid a $500 transport fee, contains a lengthy Q&A session between "Mr. Amriki" and an off-camera interviewer. It ends with his warning, which cuts off abruptly when the tape runs out.

The tape's speaker references the conflict in Darfur, the 9/11 commission, Massachusetts same sex legislation, and the upcoming US presidential election.

Al Amriki issues several bursts of Arabic, mainly from the Koran, speaking the language well, but not as a native, say Arabic speakers who've heard the tape. And he's clearly a sophisticated news consumer - quoting sources ranging from BBC's Arabic language radio to US comedian Bill Maher.

Perhaps the abruptness of the end of the tape gives the impression that there was more on it. The CSM report comes from someone who has seen the tape in Pakistan.
