The Pulitzer Prizes showcased journalism's power to shine a powerful light on the forgotten or the unknown, and the awards honored work including stories from The Associated Press revealing the New York Police Department's widespread spying on Muslims and The Huffington Post's pieces about the suffering endured by American troops severely wounded in Iraq and Afghanistan. The AP won a Pulitzer for investigative journalism, while the national reporting prize went to the Huffington Post's David Wood. Other journalism winners in the awards announced Monday included another Pulitzer for investigative reporting awarded to The Seattle Times for a series about accidental methadone overdoses among patients with chronic pain. In the arts categories, the late Manning Marable won the Pulitzer Prize for history, honored for a Malcolm X book he worked on for decades but did not live to see published. Quiara Alegria Hudes' play "Water by the Spoonful," which centers on an Iraq war veteran's search for meaning, won the Pulitzer for drama. The New York Times won two prizes. David Kocieniewski was honored in the explanatory reporting category for a series on how wealthy people and corporations use loopholes to avoid taxes.

The AP's series of stories - available online at http://apne.ws/IrNyPk - showed how New York police, with the help of a CIA official, created an aggressive surveillance program to gather intelligence on Muslim neighborhoods, businesses and houses of worship. It was the 50th Pulitzer won by the news organization. The articles showed that police systematically listened in on sermons, hung out at cafes and other public places, infiltrated colleges and photographed people as part of a broad effort to prevent terrorist attacks.
