Shahzad told Cedarbaum it took him six months to connect with the Taliban in Pakistan. He said he then spent 40 days with the Taliban in Waziristan, only five of which were devoted to bomb training.
After his training, he spent February to April in the U.S. getting the money and materials together for a bombing and planning his attack.
"I made the bomb in a car and drove it to Times Square," he told Cedarbaum.
"All by yourself?" she asked.
"All by myself," he confirmed.
Shahzad said he didn't know why the device had failed to work, and that after lighting the fuse and waiting three-and-a-half to five minutes to hear the sound of an explosion that never came, he went to Grand Central train station and took a train back to Bridgeport, Connecticut.
He also said he had chosen no specific building, but had intentionally placed the bomb in Times Square during a busy time.
"You wanted to injure a lot of people," said Cedarbaum.
Shahzad said the judge needed to understand his role. "I consider myself a Muslim soldier," he said. When Cedarbaum asked whether he considered the people in Times Square to be innocent, he said they had elected the U.S. government.
"Even children?" said Cedarbaum.
"When the drones [in Pakistan] hit, they don't see children," answered Shahzad. He then said, "I am part of the answer to the U.S. killing the Muslim people."
Shahzad was arrested on May 3, two days after the failed bombing, at New York's JFK airport as he was about to depart on a Dubai-bound flight.
Shahzad's 13-page indictment included details about his travels to Pakistan, and named the Pakistani terror group, Tehrik-e-Taliban, from which he received bomb training. The indictment also said that Shahzad received money from an unnamed coconspirator in Pakistan prior to the failed May 1 car bombing in midtown Manhattan.
"The facts alleged in this indictment show that the Pakistani Taliban facilitated Faisal Shahzad's attempted attack on American soil," said Attorney General Eric Holder. "Our nation averted serious loss of life in this attempted bombing, but it is a reminder that we face an evolving threat that we must continue to fight with every tool available to the government."
