Prosecutors: NYC man determined to bomb subways

FILE - In this Sept. 17, 2009 file photo, Najibullah Zazi leaves his apartment in Aurora, Colo., for a meeting with his attorney. When New York undercover officers and informants were infiltrating a mosque in Queens in 2006, they failed to notice the increasingly radical sentiments of a young man who prayed there. Police also kept tabs on a Muslim student group at Queens College, but missed a member's growing anti-Americanism. Those two men and friends _ Zazi at the mosque and Adis Medunjanin at the school _ would go on to be accused of plotting a subway bombing that officials have called the most serious terrorist threat to the United States since Sept. 11, 2001.
