Federal agents say that Faisal Shahzad, the Times Square bomb suspect, has waived his right to a speedy arraignment and has told investigators more about his intentions.
According to investigators, Shahzad rehearsed his plan to park a car bomb in Times Square -- three days before the actual incident. And one just day before the incident, he left a getaway car in the area, but mistakenly left the keys to that car inside the bomb-rigged Pathfinder.
This latest discovery is a sign that he may have acted alone after returning from Pakistan earlier this year.
"At this moment there is no specificity as to where he might have gone and who might have trained him to put together the explosive device that he put together which luckily did not go off," said Husain Haqqani, Paskitani ambassador to the U.S.
New York leaders are praising the work of the state's police force. However, at the nation's airports, the incident has prompted changes to the government's no-fly list.
Airlines are now required to check no-fly lists within two hours of being notified of additions to the list instead of 24 hours.
"The idea that someone would pay cash and just walk on an airplane, particularly when they got the ticket at the last minute, is very confounding," Sen. Charles Schumer, D-N.Y., said.
Shahzad has said he was angry because his friends were killed by CIA missile strikes in Pakistan. He told authorities that fears for the welfare of his family drove him to carry out the attempted bombing.
"It's looking like he was a Taliban sympathizer," CBN News Terrorism Analyst Erick Stakelbeck said. "He told investigators that the U.S. drone missile strikes against Taliban leaders in Pakistan really angered him."
Shazad made his getaway from Times Square using public transportation. When customs officials finally tracked him down on a plane to Dubai, they said the first thing he said was, "What took you so long?"
