In this picture taken Tuesday, Dec. 8, 2009, an Afghan police trainee from the United States Marine police mentoring program eats a candy as Marines search a house that was thought to have explosives during a joint patrol in Khan Neshin, in the volatile Helmand province of southern Afghanistan. The experience in Khan Neshin highlights the difficult task facing coalition partners as they work with the Afghan government to dramatically ramp up a police force known for its corruption, drug use, and lack of training.
