Atlanta rapper "T.I." had a long rap sheet before becoming one of Atlanta's most visible cultural ambassadors. Here are moments from the entertainer's volunteer and activist activities. His turnaround began in 2008, when he spent part of his 1,000 hours of community service telling schoolchildren to avoid the gangster life. This event at Stockbridge High School was sponsored by the local NAACP. (Joey Ivansco / AJC file)
