NEW YORK (ABC)-- The interrogation of Faisal Shahzad continues to yield new information Thursday. The Times Square bomb suspect waived his right to a speedy arraignment and is sharing more about his intentions with investigators. Thursday morning an image is coming into clearer focus of a bungled bomber, who likely acted alone after returning from Pakistan earlier this year.
Faisal Shahzad apparently rehearsed his plan to park a car bomb in Times Square. Authorities say he did a dry run three days before and the day before.
Shahzad says he was angry over friends killed by CIA missile strike in Pakistan and that fears for the welfare of his family drove him to carry out the attempted bombing.
Despite being on the no-fly list, the 30 year-old Pakistani-American was able to board the Emirates flight bound for Dubai. But it's his near getaway that has forced immediate changes to airport security. Now, airlines must check the no-fly list within two hours of flight time.
