A man smiles for a photograph while sitting in the halls of district court in Swat valley region located in Pakistan's restive North West Frontier Province March 19, 2010. Authorities say security has improved since a military offensive nearly a year ago cleared out militants from Swat. But police remain vulnerable to suicide attacks and residents fear the Taliban will return if the military leaves. Picture taken on March 19, 2010.
