Mattie McClinton sways her arms and calls out during a tent revival service at Union Missionary Baptist Church Thursday, July 21, 2016, in the East Garfield Park neighborhood of Chicago. Pastor Raymond Hillman helped organize the revival in response to violence in the area. Much of it can be linked to gang conflict over territory and drug dealing as well as easy access to illegal guns. There are deeper societal problems, though, including long histories of poverty and neglect by the city in some of the more crime-ridden neighborhoods. 34-year-old Lanarris Webster was shot and killed less than two blocks from the church the previous month.
