He also pleaded guilty to conspiracy to commit murder in a foreign country and providing material support to a terrorist organization.
His guilty plea may mean even more for the war on terror, since it appears Mr. Zazi has agreed to cooperate with federal officials.
Terrorism officials believe the government probably would not have agreed to let him plead guilty with the prospect of some leniency at sentencing, if they did not believe he had information that could be helpful at preventing more attacks.
“The way it typically works is: Before a prosecutor will accept cooperation from the defendant, there has to be some offer of truth at a proffer session,” says Robert Mintz, a former federal prosecutor in New Jersey and a partner at McCarter & English in Newark. “The prosecutor will want to know what that information is with regards to the other co-conspirators and will want to assess the value for other prosecutions.”
The government also has charged two of Zazi’s high-school classmates with conspiracy to kill US soldiers in Afghanistan. Both men, who have pleaded not guilty, are due in court Feb. 25. And it has charged an imam, Ahmad Wais Afzali, from a mosque in Queens with tipping off Zazi that he was being investigated.
It’s not clear what information Zazi has, but he has already admitted that he attended a camp in Pakistan where he learned to make bombs.
Outside experts believe Zazi’s information could help law-enforcement officials and intelligence gatherers in Pakistan.
“He must have information they want and consider important,” says Carl Tobias, a law professor at the University of Richmond in Virginia who follows terror investigations. “This is positive in terms of information gathering.”
The FBI had been following Zazi for some time, including when he drove from Colorado to New York on Sept. 10, 2009. In Colorado, he had purchased the ingredients to make bombs, but said he flushed them down the toilet after he became nervous when he was stopped for a traffic violation near the George Washington Bridge.
The government said Zazi had bomb-making instructions on his computer. After his arrest and the arrest of several other co-conspirators, Attorney General Eric Holder said Zazi was part of a plot to kill “scores” of Americans using bombs in backpacks, much like the attacks on the subways in Madrid in 2004 and London in 2005.
