Volunteer pastors Douglas and Magarita Barr-Hamilton roam the St. Pancras station as they look for people to help on Wednesday, Aug. 8, 2012, in London. Roaming London's transport network in blue baseball caps are 300 volunteer "games pastors" from a range of Christian denominations. Deployed at airports and train stations, they are ready to step into the most trivial or most serious situation, from a lost contact lens to a potential suicide. (AP Photo/Emilio Morenatti)
