Upon retirement from Vanderbilt Divinity School, Rev. Don Beisswenger did not make plans to go fishing, nor did he plan on going to prison. Beisswenger, however, did know that it was time to honor his commitment to the poor and marginalized. He began to work with homeless persons in Nashville and also to study conditions in Latin America, where he was particularly concerned with US involvement in training military units of other countries. After attending several prayer vigils near the School of the Americas center at Fort Benning, Georgia, Beisswenger stepped on to the federal property as an act of civil disobedience, and was later sentenced to six months in prison at the age of 65. LOCKED UP is the remarkable story of his incarceration and the larger spiritual lessons he offers for all Christians about remaining human when our humanity is tested, bringing grace to those who desperately need it and bearing witness to God's promises of mercy and judgement.
